Airtel
Not able to get UPC Code

Hi,

I am using the airtel and I want to port out my airtel no. but when i am generating UPC (unique porting code) they are not providing me the UPC code & the error which is coming

You have entered an incorrect code. SMS PORT to XXXX and initiate a new port in request.

I lost all of my balance up to 100 RS. for this messages. Called up customer care lot of times and did not get any good response..and they are just keeping the call on hold for sometime and disconnecting the call.. I dont know what to do now?? any one can tell me if there is any other way to get the UPC code please???
