[Resolved]  Samsung Galaxy S Advanced — Not replacement of defective piece

Address:

Bangalore, Karnataka

I bought a samsung mobile from reliance time out located in cannigham road,bangalore.The phone is hardly a month old and it is giving me major problems (not charging,usb port does not work,hanging). I have given it for service twice at the samsung service centre in infantry road,however the the problem has still not been rectified.When i asked for a DO certificate the contact person Mr Shashi refused to give it to me.The reliance store i bought it from is ready to exchange my phone provided I have the DO certifacate.So kindly help me out with the same.
