Vodacom is increasing my monthly contract payments for data, without my consent.

I’m being abused by Vodacom, they are increasing amounts on my contract monthly payments for data. When I tried to call , the consultant (Lebogang) was confused and very rude, she said I’m hotspoting a device that has R15 per day subscription and that led to the increase .When I said I want to cancel the contract she said it will cost more money. I’m supposed to pay R400 monthly for the contract but I was told that I must pay R2000. She said the matter is escalated to the back office but there is still no communication. Beware of Vodacom contracts
