MWEB charges for services they DONT provide after they increase the servise without leaving you a choice

MWEB decides on its own they will not supply the contractual agreed 50MBS fibre connection and will increase the supply to 75MBS and you WILL pay for it, so that happens and they deduct the funds via the arranged debit order, from R855 to R899, not a big issue. HOWEVER MWEB uses EVOTEL (awesome nice people) but does not instruct EVOTEL to increase the supply on their system from 50 to 75MBS. I have submitted queries on the MWEB application, to date not even an e-mail, SMS, WhatsApp and absolutely not a phone call. How long do we still have to suffer from hungry corporations using people like cash ***s?
