Vishal Mega Mart — Exchange Bill Not Issued

I have suffering from 5-6 days for exange my product I have purchase two nos of shirt from Dhubri Vishal Mega Mart and it's has been not fit then I again visit for exchange all are necessary procedure I have completed and their after when I go to Billing counter they are not able to make payment reply me server problem Dated 19 th April 2022 and said me give my contact no from his Security Guard for conducting me when server is reached but they no any call /msg me right now.

Today 22th April my problem is same.
I Suggest to Co. - Don't make online Bill make Paper Based Manual Bill and collect only cash. Bacause Some times Debit / Credit Card are not working for server problems.

This all Suggestions imposed Only Dhubri Vishal Mega Mart Because many time I faced this issue in this Mart
