Paytm Mobile Solutions — fraud @paytmcare

My reference number is[protected]
I registered a complaint to change my mobile number in paytm account and its about 2 weeks and nothing happened..
Everyday i call paytm customer care and they say the same thing to wait for their so called concern team to call you and they are only making fraud..
Worst service ever i experienced..
They are useless, mannerless and fraud..
Paytm is nothing just harassing the people in the name of customer service.
