BHIM — transaction failed but amount of rs 2000 deducted

Address:

226007

Hello i am bhim app user, every thing is fine but when server was not good transaction was failed but my amout of rs 2000 was deducted and there is no response from the bhim app,
There is no authentic number to which can call.
I have tried to call the bhim app number but the number in app is shown is incorrect and if there is server problem then there should be a mail to assist us as i am a customer that you will get the refund within 2 or 3 working days but what i see there is no response at all.
