just like i shut down banking accounts and
credit cards that i no longer plan to use... i would like to shut down my digital wallet accounts as well. while you can properly shut down your bank accounts,
Paytm and other wallet companies tell you that there is no option to delete a digital wallet account. this is well... not an optimal scenario. especially on kyc accounts where your id information is in record with these companies.
you might discard your current mobile number in a few years and it might be assigned to someone else and he could be able to resume your account on his phone number as he would be able to login using the OTP route or whatnot. digital wallets are financial services and your name is attached to it. you do not want it to be misused years after you have stopped using it.
