Aircel — not able to generate upc code saying my mobile number and last 5 digits of sim card number not matching

Address:

Chennai, Tamil Nadu

I have been sending port messages to 1900 multiple times and didn't get any response. When i tried to call ivr it's saying my mobile number and last 5 digits of my sim card number not matching as per records. This is all just non-sense. I have been using that sim for a last 6 years. Please help me to generate upc code and its very urgent.
