Poor service

I payed this month's fee using a different bank than I always use(that's linked to their app). On the reference slot I put account details number I got on the app, which I was told was the wrong reference, so I had to sent them the proof of payment for funds to be allocated. That was done and my services were reconnected. The upsetting thing is that almost everyday my services are disconnected and when I call, I'm told that the allocation needs to be approved first for the services to not get disconnected. It's the second week now having to call in for the same thing, clearly there's someone who's not doing their job. I'm very disappointed
