Airtel Mobile Connection [protected] — Deactivation not done on reqest and deposit not refunded

Sirs,
I received the Airtel mobile connection no [protected] on 27/04/08. with Inteternational roaming facility which was functional from 30 /04/08 . The deposit of 5500 was also paid .

Since this did not serve the purpose for communication while on travel on 30/04/08 I surrendered the same on 9/05/08 to the local service outlet in Vidyaranyapura in Bangalore from whom the sim was bought.. They did not give any acknowledgement for the same . Another letter was issued by me on 10 th May on same request .
The service outlat promise that the telehone has been discontinued andrefund will be returned after 45 days .
I received a bill sometime in the month of May and it was paid though thew telephone was presumed to be deactivated .
While i was awiting the depost back I received another bill on 12 th June though i do not know what for this bill is sent .
I contacted the outlet to seek clarification and response was totaly irresponsible with no tangible outcome .
I consider this as a totally callous attitude on the part of the compant .
This may please be looked into . I look forward to deactivate my SIM from 9 th of May as requested by me, withdraw the bill for June 08 which was charged to me for no fault of mine as a customer, return the depost of Rs 5500 back to me at the earliest .
I also expect a communication from the company for having registered this complaint and invastigate why such service outlets are allowed to function like this . Thanking you .
