Dear sir,

as my issue i have tried to contact Mr.Bhuwan who is looking at my case but he is unable to handle my case properly and gives me a false information reguarding my case.

i have submitted my sony xperia st-18i at Accel Frontline Service Ltd(sony authorized service centre) on 30/10/2012.And til now i have not recved my cell and whenever i try to know the status of my cell then they forward the deliver date and use to say that i will be able to receve my cell on this perticular date but as usual they again postpone the delivery date.
this is not the first time i'm get this type of problem i have purchased my cell on 08of may 2012 and from last 4-5month my cell is at service centre.
