Dear Sir,
I have applied for advertisement no.:- 04/ विसेआ /2020 ARO.
I filled the form and go to payment page and pay the fees Rs.700/- then after 10 sec it redirect to form but shows your previous transaction was unsuccessful on 28 Sep 2020.
I called and mailed to the helpdesk [ [protected]@gmail.com &[protected] ]o[censored]PPCL ARO they said again pay the fees and excess amount will be credited back in your account.
Next day, I pay the form fees Rs.700/- it was successful on 29 Sep 2020.

For my excess amount Rs.700/-, I contact to both [UPPCL & Bank] so many times { I have written proof also}, UPPCL say contact to your bank for refund when I contact to bank they say contact to your merchant(UPPCL).Now I am tired with contact again & again to both of them.

Still I didn't get my excess amount refund yet.
Kindly request to you please refund my excess amount.
