Motorola Solutions — service center is not repairing and also not returning my phone

Address:	New Delhi, Delhi, 110001
Website:	www.motorola.in/home

Below is the detail of humiliating experience that i am going through:
4th april: submitted the phone for small issue in power jack as it was not charging properly.
7th april: got my phone back, paid inr 3, 000 but got 3 issues (Spot in the display screen, audio jack issue and voice quality at the receiver's end) which were not there earlier, not even slight issue were there.
8th april: service center denied taking the responsibility of the new issues created and in a sense meant that i am a fraud. Motorola customer care asked me to keep my phone with me and to send a written email with all the details mentioned above.
8-28 april: for 20 days, motorola could not decide how to take care of these issues. Took more than 20-30 calls and 30-50 emails to customer care so that i can submit my phone for the repair. Most of the time, there was no update from the customer care and it was always me who has to write several emails to get response.
29th april: submitted the phone to the service center.
30th april - 24th may: no update proactively from motorola. Finally got the call that display has been changed but cannot rectify other issues. Again most of the time, there was no update from the customer care and it was always me who has to write several emails to get response.
1st june: i was told that there are some pcb related issue which are causing the other problems. Somehow i convinced the motorola guys that i am not responsible for all these issues, so please rectify the issues.
7th june (Don't remember exact date): i was told that all the remaining issues are also rectified and can collect my phone.
8th june: i collected the phone, checked the headphone and display related issue and came back. I noticed that the touchpad was too sensitive and some functions are getting activated automatically. I ignored it thinking that it is due to new touchpad and also i did not want to again go through the whole process.
9th june: i found that now there is cracking sound coming from loudspeaker which was never there earlier. I again had to call the customer care who told me to again go to the center.
10th june: i again went to the center where the technician did something to the loudspeaker and it started working properly. I took the phone back.
11th june: i started noticing that the touchpad related issue is getting more serious day by day. Some functions were getting on automatically. Sometimes the navigation keys will work sometimes wont work. But i ignored it to avoid further escalation. But after a week, the navigation keys stopped working completely.
19th june: this new issue started within the same day i got my phone back and became a serious issue within 2 weeks. I was unable to use my phone by then. I sent an email to motorola customer care again.
22nd june: i went to the service center. The manager there took the pics of pcb and told me that liquid has entered into the phone. My phone never got exposed to liquid or anything, but i did not have the proof to counter this. But my phone never got exposed to liquid or anything for past more than a year. Also, the kind and amount of rust that was there in the pcb was like it has been there for several weeks. Upen has already taken the pics of the pcb but he did not share it with the motorola.

29th june: i got an email from motorola to resubmit my device.
July 7th: i could not visit the center earlier as i was outside delhi for official work and i sent an email marking upen as well that i will visit on july 7th. I went to the center but upen was not there. The other technicians there refused to take my phone. I tried calling upen, messaged him several times but he chose not to respond. I came back from the center. I almost gave up and accepted that the phone has been destroyed thoroughly. But motorola guys told me that i can submit my phone after further communication.
July 30th: i got a call from the owner of the center and he told me to submit the phone to the center.
Aug 19th: as i was not in delhi, i could not visit earlier and i informed the owner of the center accordingly. I want to the center on 19th. Upen (The manager of the center) asked me to wait for 30 mins and again gave my phone back.
Sep 21st: finally i submitted the phone to the center after writing several emails to the customer care and getting the go ahead to submit the phone.

Now it has been another more than a month that my phone is still with the service center and they have no update on when will it get repaired finally. I have not seen such a pathetic service anywhere. Kindly help me out.
