Should I leave FNB?

Good Morning

On the weekend I was moving to a new place. When I got the I found a new meter number. I bought electricity for R100, I tried to enter the coupn and it rejected. I thought the meter had been blocked. So i contacted the electricity company and the meter got sorted and still my coupon didnt enter. I checked the meter number it wasnt the same. The meter number was my old meter number. On Monday I bought again. I had to edit the meter number 3times on the app. It keeps reverting to the old meter number when I enter the new meter number. This morning I entered the new meter number checked it and it showed me the new meter number. Yet when I got to the coupon screen it showed my old meter number. I bought R500 electricity. That was my last money. I contacted my banker got no help. I need that coupon to purchase the electricity. If you can then please change the meter numbers so I can be able to load the coupons. Old Meter Number ***: New Meter Number ***

Please don't call me unless you will revert or correct this transaction. And Please don't tell me a story that you cant. If I cant get a responds from you by 12pm today. I'm closing my account. You always advertise your app as the best. Yet for the past couple of days it showing me to be the worst.
