Sony Ericsson W150i — Faulty handset/poor customer care service

Address:

West Delhi, Delhi

Hello Sir/Madam,
This is a complaint regarding a yendo model that i had bought in november 2011. The IMEI is[protected]. I had bought it from MNM Trading Solution Private Limited(Pataudi district, Gurgaon) on 20th November 2011. The invoice no. is[protected].
The phone keeps getting hang, it vibrates even when there is no message/call, it switches off on its own. Sometimes when the phone vibrates, it continues to vibrate for 5 minutes! I had given the phone for servicing but the same night, it again got switched off on its own. I am fed up of this phone. I am fed of changing my handset again and again. It's very irritating.
I have taken this phone to the service centre twice but the problem still persists. The second time, they had not even recorded my visit. I had even asked to give me a letter(jobsheet or whatever) with the details of what they had done. But they refused to give me saying that they do not give it in case of just software updates. It is not possible for me to go again and again to the centre as it is not even close to my place.
I had asked the service centre people if this problem can be fixed permanently and if the handset can be replaced as the problem is inbuilt but they had refused.
Also, i have heard that there is a problem with the entire handset lot. I have showed this model to many shopkeepers(Sony ericsson dealers) and they all said that the entire yendo lot is faulty. All the handsets have some problem. I know another person who has this model and she also faces the same problem. You can cross-check this information. There is problem with all the yendo handsets.

So I do not want a new handset. I want another phone. I am fine if it will be of a lesser price than this one(I had bought this for Rs.5,000) but kindly do something. Please find a proper solution. I have wasted my 5,000 rupees but i cannot afford to do so.

I request you to kindly look into this matter.

Regards,
Devika Mittal
