Service delivery failure

I to have a problem with Vodacom’s R100.88 penalty for debit order that fails. They disconnect you for not paying this, but as I have trying to get through to them, I RUN A BUSINESS, which requires my internet to be ON. During SEPTEMBER, I had do log 11 (please take note 11!) queries for fibre being of. But I have no right to fine them for that, THEY HAVE A RIGHT TO CHARGE ME R100 for a payment that was a day late, but I am not allowed to complain about 11 days of either intermittent slow speeds or no service at all. This really sucks Vodacom.
