I disconnected my mobile no. 9731600802 (Airtel) after paying all dues in June. I am yet to receive the deposit of Rs. 300 even after close to 11 months. I have provided all documentation pertaining to my new address and even given my bank account number since they promised to credit my account. I have escalated to their call centre, personally went to their office and inspite of several commitments am yet to receive the refund.
