Airtel
Refunded less amount out of deposit

Sir,

I had purchased a post-paid number from airtel for which I had paid Rs. 250/- as security deposit. At that time the company told me that it is refundable at the time of disconnection.

Now I have converted it into pre-paid number & they told me that your deposit will be refunded via courier & you will receive a cheque for the same. I paid Rs. 250/- as a deposit but I have received only Rs. 77.67/- as a refund.

Please look in to the matter & help me get full Rs. 250/- back.
