Paytm — mobile number updating

Address:	Hyderabad, Telangana
Website:	Paytm. In

I had been using my old number ([protected]) for my paytm account, recently I had updated my Paytm account with new mobile number ([protected]) but PAYTM showing an error that " this mobile is registered with another account ", the fact is that PAYTM account with the number ( [protected]) was deleted recently..

I don't know why still this error is coming for my account.
.

Even I had given a complaint in their portal also but it is of no use, as they are not responding to my issue.
.
So please take necessary action against them.
