Mweb confused and ***********

Contacted Mweb for fibre. Sales got all my details, then sent Evotel to install last Monday. I contacted Mweb on the day to request for the router and was told to wait for the courier company to call me. On Thursday I called Mweb to check, was then told I need to pay for courier to deliver, paid sent proof. Received messages still asking for payment, the app has incorrect info, am now being told I have an active line from another service provider which I must cancel in order for Mweb to proceed. They insist they did not send Evotel to install . So messed up. Am still to get a solution as I never had fibre and only communicated with Mweb. Horrified and distressed as I need internet to work.
