Videocon Mobile B - 1666 — defective cell

Address:

Patiala, Punjab

I have purcase a videocon mobile phone model B-1666 on 22 May 2011 through home shope 18. Within 4-5 days its display was lapsed. I was submit same to service centre in patiala it was take a month to repair the same and they will return my phone after 35 days stating that it will be OK. Now when I am calling somebody from that phone the ring from other side will not hear on phone and the person whom i am calling will listen me but i am not hear his voice on my phone.

Plz suggest me some solution for that. Thanks
