Fastrack Communications Pvt Ltd - Fastrack Communication Ltd not replaced defective lemon mobile within Warranty

I have purchased Lemon mobile model number iQ707 on April 18th 2010 from Matta Mobile World in Chakrata Road, Dehradun. My purchase invoice no. is 419 my handset’s IMEI No’s are 351612040118330 & 351612040118348. After a few weeks it has many problems. After sometime my mobile got switched off automatically and after 4-5 seconds it got switched ON. It has a warranty (warranty card no. PN5839002857) for one year. I have got the same problem more than 16 to 17 times within last 10 months. On 25-11-10 I have given my mobile for repair to Authorized Service Centre(ASC) of Lemon mobile at Dehradun i.e. Ujjawal Telecom & they said me there was a software issue in my handset and they upgrade it and now my handset will not face any problem (Job Sheet No.: LASPUPW042R830 dated 26-11-10). But My handset again facing auto shut down & auto ON problem on Saturday 05-12-2010 and also its Phonebook icon was become distorted, it seems a dotted strip instead of the original phonebook icon. When i saw it then again it automatically shut OFF & within 2-3 Seconds auto re-started then the icon appear as its original i.e. the problem of dotted strip disapear. I contacted with sanjay.taneja@lemonmobiles.com regarding this issue and I also contacted the ASC (Ujjawal Telecom, Dehradun) & told this problem to Mr. Roshan (Head of ASC, Mobile no. 09897388800), as he said I handed over my handset once again at Service Centre on 6-12-2010. ASC personnel could not able to resolve my problem that’s why it again arises. I have asked them to replace the product, since it has the warranty. They have not accepted it, and they said that they will service the mobile. Even after the service, I got the same problem. Then they send my mobile to Lemon mobiles head office at NOIDA, there Mr Ramvir singh (Mobile no. 09999760997 & 01204048000) told me they will re-place my set with new one but after 20 days they send my handset back to Ujjawal Telecom,Dehradun. When I go there to collect my phone I found that was my old phone. When I asked to ASC personnel then they said there was a problem in my set’s PCB & at Noida centre this problem has been resolved and returned my phone to me(Job Sheet No.: 424 dated 06-12-10).
But now again on 12-1-2011 I faced the same problem of auto shut ON/OFF and distorted phonebook icon. I am asking them daily regarding this issue, but there was no proper response from them. I want them to replace my mobile with the similar mobile or refund my money.
