BSNL — UPC - PORT code not received

Address:

Chennai

I have tried n number of times to port my number from bsnl to other operator but i have not received UPC code.
From yesterday i have send several messages from my phone. Every time BSNL deduct Rs.1.20/- from my account. But UPC code not yet received.
When sending message, after 3 minutes a message shows your request is delayed. Then after 5 minutes a message shows your request could not be processed.
I have tried n number of times. Every time they deduct Rs.1.20/-. But PORT UPC code not yet received.
I have talked to the customer care also. They simply say "technical issue, please wait". Please take some action
