Webafrica must fall

Hi I'm with web Africa since COVID hit and did a upgrade to a 40 Meg line to try it out but saw it was not faster than the 20 Meg line so I downgraded again back to the 20 Meg line and I knew there was a 30 day like turn around time back to the 20 Meg line but last year I saw on my statement I owe them money when I contacted them via the WhatsApp platform the lady explained about the 30 day turnaround time back to the 20 Meg line and payment that had to to be paid etc so I forward her or them the pop I had of the debts that went off but she kept on that I need to pay the outstanding balance,but I told her I'm not paying that because I have my pop as evidence.when I log onto there website the outstanding bill is still there witch I think it's crazy on their part😡. Friday morning we had loadshedding and when the electricity came back on my router was not working because my WiFi icon was there but no internet,I went onto the WhatsApp platform but only got a message back from the bot saying that the Western Cape had a problem.when I return home from work it was still down tried the WhatsApp platform again but had no response, Saturday it was still not working and no reply from the WhatsApp platform of what the issue is or what can be the problem is,it's the third day now with no reply or assistance from webafrica I think it's very unprofessional from a isp provider to keep customers on a piece of string if you have paid for the servers and I'm now at a point that I want to cancel my membership with them because this is very upsetting.
