Vodacom - Dissapointing

They don't the 1 star, but there is no option for zero stars. I upgraded my contract and the new router was delivered end November. I informed them my sim for the contract that is being upgraded is lost and I need a new one. After countless calls, the sim is still not active!!! As per Vodacom's instructions the sim has been been put in and out the router and in alternative mobile devices, with no luck. I have to pay, but I am not getting any assistance or use of the contract. I went into Vodacom in Greenacres and was advised in order for them to assist me I have to pay R299!!!!! Pay for their incompetence????? I phoned Vodacom once again today and now the sim is blocked. I was told I was not suppose to get a new sim and that Vodacom had to do a sim swop, which was not done. Now after almost 2 months they want me to buy a new sim card, do a sim swop and pay for their neglegence? I want to cancel the contract, seeing that it is not active on my side, but was told I can not cancel. Life is busy, where do they expect me to get time to sort out their **** for them?????? Would love to know which branch I can go to who will be able to assist me in cancelling this contract as I am paying for nothing.
