Atrocious Service - Nothing but empty promises!!!

I DO NOT RECOMMEND the use of this service for business or personal connectivity. I am an online tutor and as such rely on my ISP to be able to earn an income. No Service = No Income. I have been struggling with this service for months now. I have exhausted my airtime calling after them and the matter seems to remain unresolved. Recently they installed new modems and set everything up, the connectivity was better but inconsistent. I reported this again last Thursday because one can get fed-up with loss of income. They escallated it because the call centre has limited resources to resolve issues. Friday I called again to follow up (Day 2 of NO connectivity and NO INCOME) and the escalated it with urgency again by a gentleman in their India based call centre and I would have feedback from Technical Department within 24 to 72 hours from Thursday when I first reported it. Hahahahahahahaha. They missed their calling they are a bunch of comedians. I just called again: First call they can see I am connected to a tower far from my residence but cant connect it to the tower 1km from my home???? Put on hold and they then hung up. Second call within 5 minutes, the lady put the phone down in my ear. Shocking right but not the first time while calling their customer care line... Third call within 20 minutes, Mpho informed me that the matter needed to be escalated AGAIN and he could not give me any turn around time because he doesn't control technical's schedule???? He can't help me because he can do only so much and sorry for the inconvenience of having lost a considerable amount of income and students cancelling their subscriptions to learn with me (so future income also lost). Yet they expect their bill to be paid on time in full and how the hell do I do that when they are robbing me of income by not providing the service I was promised when signing up??? I pay for a 30mbs line but I am lucky if I have between 1 mbs and 5mbs. Sound fair? Don't torture yourself by subscribing to this service, I ignored all the negative reviews on Hello Peter and Facebook, but I have now paid a fortune in school fees and can honestly say they were not wrong in their reviews. Don't do yourself an injustice by joining this service, you will kick yourself after the first few months, as I have. If I could rate them in integers I would because a one star rating is too high!!!
