Corporation Bank — upi transactions failure

I, a customer of your bank am facing issues with upi transactions both in the native and third party application since a week. As per as i know this issue is being faced by other corp users as well.
I have been patient with the issue for the past few days but since it's my primary bank account, i would like you to resolve this issue at the earliest.

Upi has issues while sending and recieving money. I had contacted customer care multiple times but in vain.

Looking to hear from you at the earliest.
