No internet forore than two weeks, technicians don't know what they're doing

Technical support from Telkom is appalling, I don't understand how they refer to themselves as technicians when they fail to resolve a matter for 2 and a half weeks, no feedback on progress and you constantly have to call them to find out what's happening, they set a commitment date that they can't even stick to and then the billing side expects you to pay your full premium because the fault is still open... For more than half a month I've had no internet, you have to be dealing stupid to think I'm gonna pay the full price. Fix my problem, this is why you guys are losing customers, I need to find out howuch it costs to cancel and say my good riddens. Your customer care doesn't exist at this rate
