Mpokket — Unable to register new device

Hello Team,
I have my new phone now and the previous device was damaged due to an accident. I have downloaded the application however now when I am making or withdrawing the payments it's stating I need to install the application in the old device to proceed.
Can you please get this looked into on priority as it is delaying my payments and other activities?
Your assistance on this will be much appreciated.
The contact number is [protected] & the same one is the registered number for the account with mPocket.
Regards,
Kalyani
