PhonePe — payment failed on phonepe and didn't receive refund

Dear sir,
I was using phonepay for electricity bill payment and transaction got failed due to technical issue.1020 rs deducted from my account. Now its been 15 days they did't refund money and now they asking me to reach bank for the same.
Worst service they have given as i don't have time to reach bank. Also they dont have any helpline number.

Pl look into the matter

Thanks
Ajay
