Airtel — problem with the outgoing message since more than an year.

Address:

New Delhi, Delhi, 110059

I've already lodged this complaint with Airtel customer care several times in the last one year. But no resolution has been provided till date.
Once again I'm briefly telling you the issue, Since the day the have started using this number ([protected]) which i earlier bought in Jammu then after moving to Delhi this number was transfered in Delhi (NCR) circle, whenever I'm roaming with this number my outgoing message service is barred and now since yesterday morning my outgoing message service is completely barred after making some complaints again, since today morning I'm able to send message to some numbers but can't receive the message from the same number.
