Airtel — spelling mistake in name registered with airtel

I submitted my driving license for my Airtel prepaid connection, somehow my sim stopped working when I approached Airtel store they refused to provide me a replacement as there was a spelling mistake in my name and my father's name.

And now when i call customer care they are like we cant do anything from here.
such a huge mistake by airtel cant be ignored. Till date I tried several times but every time i get same answer nothing can be done and I can not get my number again.even though mistake was done by airtel it is me who is suffering airtel is the most irresponsible operator of the country.
