Jiomart — Unable to login in jiomart

Website:

www.jiomart.com/customer/account/login

I can't able to login for the past 10 days in jiomart application and website showing invalid login and invalid otp even though I have given the correct OTP.I have already complaint this issue 10 days before to the jiomart customer care but they are not looking this issue seriously and everytime they are saying that we will get back to you once we get an update.I have tried all the steps like clearing all data and cache but not resolved yet.So kindly do something from your side to solve this issue as soon as possible.
