Afrihost service reprehensible

I have been having problems with my Internet speed that should be 250mbs but runs on an average of download ±50mbs and upload ± 15mbs. I work from home and is totally dependent on steady internet. I am losing customers because I am battling so much. I have been on Afrihost WA group several times the last of couple of months, I have sent emails alas the problem still persists. I had no option but cancel Afrihost as my Service Provider, only to see that they want to cancel my service 01/11/2023. I cannot wait until then and lose more clients. Afrihost used to be excellent, now they are unresponsive to emails, expecting me to do their technicians jobs. I am so fed up, yet the deduct R1136 off my account religiously every month, without the benefit of proper service or speed. I want my contract immediately suspended so that I can make use of another Service Provider that is prepared to come to my house and assist if there are any problems. I also want a refund on all the months that I have not received 250mbs up- and download speed. Afrihost, you service have declined drastically and if this is the way that you treat your customers without responding or assisting properly, you are going to lose more clients.
