Vodacom the circus

Vodacom you are pathetic, i was called to do an upgrade by a very rude and aggressive sales agent. After doing my upgrade I saw that there cheaper offers online. I then called Vodacom within the 14 days to cancel the upgrade. Since then I have been charged double for this contract that's supposed to be cancelled. My case is constantly being escalated. Now the call centre says I should call RAM to get the reference number. The same RAM they sent to collect the device. A device they said they didn't receive. I was billed for contract with a device I don't have with me. I have emailed their customer care center, they are not helping at all. I just want to be reimbursed the extra money I paid on this contract. I have been a loyal vodacom customer for many years. So this is how you treat your customers. Pay me back my money. Not going to continue doing contracts with you.
