Shocking service rears its head before trial period is up - THANKFULLY!!

I am still in my trial period with Afrihost and I can honestly see why so many people comment on how their support service has deteriorated, to the point where not even a supervisor can call you back in the specified time. On Sunday afternoon (with no storms or p:ower cuts) we were suddenly left with no internet service. I rebooted and waited 3 hours before logging a complaint although I could not find any reason for the lack of service. On Monday morning the saga or attempting to get some semblance of service started. In spite of my advising Afrihost that I have internet access when connected directly to the Vuma box I was told the fault lay with Vuma, by 9:20 I had a fault reference number and thought all was well, a couple of minutes later the internet was up again. Well, since then I have spend all of Monday from 8am - 6pm trying to get resolution; again today from 8am to 2pm to try get some resolution and the "supervisor" that was going to assist me and call me back in 10 minutes at 1pm still has not bothered to phone back (the reason being that I had spent so much time trying to resolve the issue and hotspotting my phone in attempts to fault fine, that my battery was almost flat - so I was going to take the laptop, cables and a phone charger to the Vuma box and wait for his call). Needless to say after talking to no less than 9 people today, I am still sitting on the floor trying to work, with no phone call or resolution forthcoming. I have now sent my cancellation notification to Afrihost and will certainly NOT be taking up their services when the trial period is over! Afrihost, for an ISP which came highly recommended, I can only assume that peoples perceptions of service in your industry are very low and you are unable to raise the bar in any way.
