MTNL Delhi — Dolphin Prepaid Issue

Address:

New Delhi, Delhi

since past 15 days facing incoming issue with my dolphin prepaid No. [protected].Facing Incoming problems, on incoming am not able to hear voice from other side. Complained Twice but issue on my side doesn't solve. First complaint was launched on 30th March 2015 under complaint no. 732883, Nothing happened, again i launched complaint on 8th April 2015 under complaint no. 736328, again nothing happened, Today on 10th April 2015 I called 1503 customer care no. to rectify whether any action has been taken. They told me that problem has been solved at there end. So customer doesn't exist here MTNL is resolving problems at there end only, not at customer end. Kindly refund my payment of 2100/- approx that exist in my prepaid, so that i move towards another company.
