Paying for internet but no access

I have been without internet for almost 3 days now. Initially my sim was blocked by MTN saying the device is incompatible, which it definitely is not. The line was requested to be unblocked. I called again, no escalation could be done now they were saying it would take 2 hours and not 30min - 1 hour like I was initially told. After the two hours I called back again. Different consultant of course. After resetting, rebooting and reconfiguring my router it was still not working. I called again. Different consultant. She said the issue was with the line on Afrihost side. I emailed and called again the next day. The consultant had no idea what was going on and escalated it to MTN, which is where I started. How is this acceptable. Why is it that paying customers have to chase you around just to provide basic service. You are supposed to be calling me. Oh and when I asked where I could log a complaint there was no forum for that. I posted on your Facebook page and you just deleted my post with no feedback or follow up.
