Afrihost Fixed Wireless

I started experiencing problems with my Fixed Wireless around the 16th of December last year. At that time they had published on their portal that there was a problem with fixed wireless in certain places. I thought that affected me too, until it was published again that problem was resolved. Then I reported the matter to them. They tried to troubleshoot but nothing succeeded. Until one technician suggested that the new SIM was needed to solve the problem (this was on the 24th of December). I'm still waiting for that SIM. The stories that I keep getting about the warehouse aren't my problem, my problem is what I've paid for. In December the usage in the account was just under 50%, I have lost the rest of the data and they won't refund me some of my money even if its not my problem. Today its the 13th again I will lose out on Data and there will be not refund. What am I paying for??? I promise that if this is not resolved and I don't get my SIM tomorrow by end of business. I will be sending my cancellation Tuesday morning and I would like to be refunded all my money.
