Please don't activate PAYTM POSTPAID, initially they will mislead customers by saying it's free of cost for a month, but if you use the limit and repay within time also they will charge high Convenience Fee. The worst part is PAYTM POSTPAID don't have any customer support .. This is rediculous!!....for the name sake purpose you provide 24x7 customer support that too Preloaded Chat option where Customer has no option to put his words!
