Dissatisfaction with Afrihost

I joined Afrihost about 2 years ago, and everything was fine until about 2 months ago when I started experiencing connection issues. I've tried numerous times to contact Afrihost for assistance, went through all trouble shooting steps on Twitter but still I was experiencing a poor connect. About a week ago I spoke to Ntombi who was so rude and just basically told me that there's no coverage in my area and that I should cancel. I asked her how so when I've had coverage for the past 2 years. I asked to speak to someone else. A gent then called me and explained to me that RAIN was no longer available on Afrihost - this I did not know. He also advise that they switched me to a new tower that was further away hence the poor connection. I then asked to switch to Telkom as he advised that the connection would be better. We checked my address and he confirmed that I have coverage. My issue here is that I've been paying for basically nothing as I've had limited access. Even at this moment, I have so much of left over data that I cannot use and it just expires. Spoke to someone this morning who was not helpful at all. I want to be reimbursed for the months that I had no coverage.
