No assistance with over-billing.

Logged a request months ago to have my tariff changed from the old R599.00 PM to the now R349.00, as updated on Supersonic's website. Have spoken to 3 different agents, all promising me that the issue will be rectified. I am being billed unfairly at R599.00 despite having requested the tariff change. Now I am forced to carry the costs, paying R599.00 monthly instead of R349.00. This has been going on for months. When I requested why the clientele was not informed of the tariff change, I was told that it is up to each client to REQUEST it, specifically. Take a look at other ISPs, they will upgrade your package, or drop your tariff. They won't just try and ***** from you. I think it is about time that this matter goes to court, since I am not getting any assistance, at all, with this matter. Have done my part on requesting and calling, when never receiving the callback, as promised. ''System is offline'' is the excuse I get as to why it cannot be rectified immediately. Been a loyal customer for plenty of years. Think it is drawing to a close, now.
