[Resolved]  Amazon India — bought tv serial number mismatch and technical issue with tv

I have bought tv online from amazon.in. It got deliver as per schedule. Then i have followed up for the installation with company service center (Vu technologies). They did installation too. After that when i start using tv. It is getting hang when i do any thing on installed browser. I raised the complain to vu technologies. I got the call from vu technologies on 22 oct, 2019. Then say it could be software issue and will take 2 day to rectify the same, after 2 days on 24th oct, 2019 technician said it is not with software it is with hardware and gave the report too. I have escalated the issue to amazon. But they are not accepting vu technologies report and forcing to schedule service visit by amazon only. But some how on 24th oct while talking to customer care they understand the problem and told me that it would be replaced first. I agreed on the same and asked them to raise the request. While trying to raise request they said that product serial no is not matching. And they confirm this problem is from there end. Still i showed my patience till end of the day and agreed that they will escalate the issue and copy me in mail. I have not received the mail. Hence i called them gain yesterday 25th oct, 2019. Again call started from the beginning. Again i have to explain the issue and make then understand that service visit from vu technologies has been done, but amazon customer care not agreeing on previous day conversation. Call went to almost 1.30 hours and transferred to many department. And each department is saying they are concern person only for 1 issue as it has two. 1. Technical issue 2. Serial no is mismatching, yesterday call it was agreed by on of the executive that they will refund money and transferred the call to other department. At the end of the day executive said he will transfer the call to his senior. Bu later he said that he is busy and will take atleast 30 mins to get free and after that he will give call back to me. I gave almost 1.30hrs time call me which is much more than what they requested. But i did not received any call till now. I have lost my patience as almost 6-7 hrs has been wasted and talked almost 10-15 executives. Attaching service engineer report. I am looking for your assistance for resolution and get my product return and refund and compensation as well. Please do the need full.
Again followed up on the request on 30th oct, 2019. They said till now no one has acted on earlier request hence raising new one. Hence created new request to correct serial number in invoice. But still no update.
