Charged for a phone I don't even have

Once again Vodacom you have messed up!!!!! I took out a new contract, went into store to do a sim swap, it wasn't requested. Was pushed from person to person in customer care (6 different people to be exact) nobody could rectify the issue and were given a 100 different excuses from the number has been deleted from the system to the account hasn't been finalised. Was told to go back to store as they are the only ones that can fix it. The lady was disgusting rude telling me it was 'back office fault and not her fault. After 4 days of back and forth I cancelled the damn contract and the phone was collected. I confirmed with cancellations that I wouldn't be charged they so no. And surprise surprise I have been debited the contract amount today for a phone that wasn't even used. Not only have a paid for a new sim, I have also been debited for a phone I don't even have. Well done Vodacom!!! Never dealt with such an ***********, rude, absolutely disgusting service provider in my life. #sickandtiredof****service
