[Resolved]  Nokia 6208 — nokia set not accepting my sim card

Dear Sir/Madam

this is to inform you that on 11th Aug 09 I hav purchased Nokia 6208 from Mobile Store, South Ex- with an offer of vodafone sim card woth 100/-. But AS LATER ON I inserted my MTNL sim card in the hand set the set was not accepting my sim card. But the set is accepting other sim card like vodafone n idea. AND my MTNL SIM CARD is working in any other set.
On 18/08/09 when I went to the mobile store from where I had purchased my set initally they refused to to attend saying show it to your MTNL office or go to nokia care. This was really very disguisting with out using the for a single day why should I go to Nokia care after paying such a dear amount. After 15 min of argument they so my set and asked me to go to Nokia care saying we can't do anything.
When I requested them to replace my hand set they refused me saying 48hrs of replacement time is over.
This ws again to my astonishment that this 48hrs of replacement policy they didnt inform me at the time of purchase and they themselves have aggred to misguide me.
On 20th Aug Ishowed my handset to Nokia care Lagpat Nagar. They suggested me that the hand set will go to the company and then only I'll get my hand set. But without using the phone for a single day and I return the phone to the company there no fun in purchasing a brand new phone after paying such a great amount.
This is my request to you that kindly replace my set as soon as possible. As Im using Nokia set by the past 6 years I dont want to loose your brand equity.
my set details are as follows;
