The worst service

Again the worst service you can get from any service provider. I was upgraded again by a telemarketer from Vodacom rewards and just as per my previous 7 complaints again they cannot deliver in time, this time I am cancelling as they promise but never deliver. I am done, I was just *****ed over and over by them, they stole 4 months of money without delivery the first time and now again doing exactly the same,
