AfriHost ripping clients off

Have been with Afrihost for 5 Years and 8 months! But it seems that customer satisfaction and service delivery is no longer. Moving house left me no option to activate Fixed Wireless LTE with MTN sim. Paid for the devices out of my own pocket. All was working fine until I started noticing the connection dropping to the point where I could not even open a local website on any of my personal devices. Logged a ticket on the 27th of July, which is still not resolved, where I was told to go to the non working MTN website to see what the problem is. Sat on the phone with AfriHost for 1 hour plus trying to sort out the connection lag, but that was unsuccessful. Fibre became available in my area and I opted to STAY with AfriHost even after the failed service delivery with the Fixed Wireless and just prayed that I won't be facing the same issue. Then at the end of August I received an invoice for R999 for cancelling the Fixed Wireless LTE before the 3 month period. How can AfriHost still charge me for NON SERVICE DELIVERY???? So I am expected to pay for the monthly service and then still pay for something that does not WORK???!!!! I am disappointed with AfriHost. They started out well and I thought they were different from the other service providers. But it turns out that AfriHost are exactly the same as the rest, rip the customer off, no service or customer satisfaction and still expect the customer to just smile and pay for it.
