HOURS ON HOLD, three months of no Internet, systems down

We've been using a Telkom ADSL line for a year now. Three months of no Internet. Every time we call they just say that the problem is already logged. After we've called more than 7 times, we talked to the manager and asked when it will be fixed, but unfortunately he did not know.... Like really? They won't even find out for you and call you back, it's very straight forward from their side; they don't know. That's it. Now that the Internet is on again and we have to organise for compensation, they're systems are down, and they can't really compensate. They also can't organise the compensation on our behalf. We have to call many times, hold for literally 30 minutes or more sometimes, just to find out that we have to call back another time. Telkom is the worst service provider we have ever used.
