Ombudsman needs to deal with ************ businesses like MWeb and hols them accountable

So I got a call from vuma regarding Fibre and I agreed to take a contract. They asked which provider I preferred and I had no preference and asked the sales agent to suggest any and she suggested mweb. Mweb then called me and I selected a packages for 449r pet month of which I asked to start monthend as it was first week of the month and I already paid for internet that month. 2 days later the router was delivered and I didn't bother to even unbox it. To my horror mweb started to run a debit on my account which bounced back and my bank account went on to arrears. It was even wrong amount of 625r . An agent then called me to which I asked why they were even trying to collect and why wrong amount. It was back and forth and syd eventually Conceded and said they will investigate. Till this day I never got feedback but mweb went on to try debit willy nilly for months. When they realized that was futile they sent me a text to say I'm liable to pay a cancelation fee of over 2000r and now I'm being called by Dalys and getting threats via sms. As a young South African I wonder how businesses can get away with malpractice and abusing consumer information. Where are the statutory bodies that govern such institutions or the ombudsman. Surely those are in place to negate such. I see gazillion of complaints from consumers about mweb but seems we are helpless. They r running a tab on my account which I'm liable to pay to the bank for all thsse deductions on my account which I can't even stop. I was told it will get a debit order if 449 on the 25th n from day one they debit a different amount via stop order.
