Incorrect Billing and Poor service

I installed fibre in my home via mweb. They have started billing me and deducted money from my account although I have highlighted that I am unable to use the internet. In addition, they ignore my requests to cancel the account. I have been on the phone with them and the was a time when I was put on hold for 17 minutes but they refused escalation to solve my complaint. They instead put me on hold, asked questions, put me on hold and it went on until about 17 minutes.

I have contacted my bank to stop these debit orders but mweb has failed to contact me with a resolution or cancellation documents. It has been over 16 days since they installed the fibre in my home.
