C-fibre making mistakes and can’t correct them.

I ordered C-Fibre from the sales consultant , paid and checked if they have coverage on my premises. All was well until I followed up on my purchase and order and the sales consultant (very rudely) told me that I would have to cancel my order and they will refund me. I did the cancelation with the consultant and received my refund. Immediately phoned Mweb ordered fibre, installation and activation was done in a matter of 3-4 days. Just to find out when Mweb wanted to activate my line that Cell C-fibre , activated my fibre line under their name, and made it impossible for Mweb to activate it. This was done without cell c sending any technicians or routers/fibre products. And it was done after I cancelled what was only an order! Tried to phone C-fibre for them to switch it off , but they said it isn’t possible I will have to wait another month. Now I have Fibre which would work but cell c has occupied my line forcing Mweb out. Another month withou fibre, and Cell C Fibre’s bad attitudes and help. They don’t provide any solution for this and says it out of their hands. Where they made the mistake in the beginning to tell me to take C-fibre and that they could provide me.
