Bad service from vodacom call centre & activation

I took out a new contract with Vodacom the day before yesterday, and they delivered the next day which was excellent, but then the nightmare starts, you have to activate the phone/tab simcard, I phoned *** the activation number I held on for 3/4 hour and while holding on phoned the same number from my cell phone and while still holding on, on the other phone waited again 1/2 hour, eventually took the option of the call back (which they tell you will be in an hour) needless to say still waiting for the call back, eventually phoned now again this morning held on, on my cell for 1 hour just to be cut off, so NOW I HAVE HAD IT WITH VODACOM SERVICE if you phone the customer care number to speak to a manager or someone to help they just tell you that is the only number you must just hold on so please tell me what should one do now?
