Mweb - Absolutely absolutely poor service!

I have been a loyal Mweb for a few years. In November 2017, I decided to change from ADSL to fibre internet. I got a quotation from another service provider for this. I called Mweb to cancel my contract with them but they offered to better the offer that I had received. It's now February 2018 and they still have not installed their fibre. I have called them numerous times and they keep telling me that either they have a backlog or their service provider is delaying. This is as unbelievable as it is frustrating. They have deducted money from me for this but they haven't delivered. Absolutely unacceptable and extremely unprofessional!
