Constant accounts issue - now account suspended

So I have a high stress job and therefore chose afrihost fibre as my service provider at home because I often work from home to host and attend online meetings. I find the 10mb fibre is more then sufficient, and being able to monitor my data on the app, this has been the best solution for me. This has been fine up until recently when the app hasn’t been working properly. I’ve had the odd “this service is currently unavailable” message appear. On top of this, for the last few months I have been getting a message saying there is a problem with my payment. It mentions to settle the account, which I try do, but then get the same error “this service is currently unavailable”. After struggling I’ve manage to get the account paid each month. So this afternoon as I am sitting in a meeting with my headset I get an sms on my phone saying “we’re having ongoing problems with your payment...” about 5 minutes later my call just goes dead and I get a message about my account being suspended. My manager and many other managers on the call would now give me issues about working from home as I do not have a reliable internet. I have in fact suggested to many of my colleagues about my success with afrihost, and now I have to deal with the shame of pushing a company that is clearly failing me. For many years afrihost has been the most professional and stable isp, but if anyone has advice or better recommendations, please let me know. I may have penalties to pay for ending my contract with afrihost, but I certainly can’t afford this level of unreliability.
