Airtel — unable to activate my postpaid number [protected]

Address: 560100

I am using this number [protected] for almost 7 years. I have ported the number from tata docomo to airtel 6 months before. During the porting, i had submitted all the proofs they wanted for the porting. Also the address verification also completed by airtel guy. Now for last 2 weeks my number is in suspended status due to insufficient documents. After all the verification done, not sure why they are asking to resubmit the document. Still i had submitted the requested documents last week friday. They told within 24 hours my number will get activated. Now i have crossed 6 24hours still it is not activated. Now i am feeling like made a big mistake by porting the number to airtel because of their pathetic customer service.
