Generally their apps do not give any trouble and I use multiple services of Paytm but I am so much troubled with their customer service unprofessional and untrained staff keep repeating scripted language do not want to listen to their customer complaints . I had just two simple queries for which I had wanted their support . First one was to close my seller account where I am listed as a vendor and secondly I wanted to update nominee on Paytm money but there is no helpline for these services you raise online trouble ticket no use, you send email there is no response or they will revert back with some other solution for a different paytm service . sounds funny but I am frustrated to the core do not know how to take things further now .
