Sony India — consistent problem in sony xperia mobile phone

Address:

Jodhpur, Rajasthan

I have purchased Sony D2202 Xperia E3 on 23 0ct 2014 from M/S Space electronics, Jodhpur (rajasthan) vide invoice number 44359. Since its purchase it gets hanged regularly and person calling to my number finds my phn switched off even whn it is not. Initially it was told by your service centre to use nano sim(instead of normal sim cut to fit in the phn), but it didnt solve the problem. Then the service centre again asked to for some formatting and software updates but all in vein, problem still continued. Service centre name- M/s Nehal techno services, jodhpur. Ticket id - [protected] So I am fad up with this mobile, it seems that it is a defective phn. So I request you to please replace the phn as I am not at all satisfied by it. I hope you will take appropriate action for its replacement, presently the phn is with service centre.
