Call center's is not giving service to your clients

We got fiber is our area. Due to poor service with our previous ADSL line provider we decided to join up with Mweb. The product , price and offerings look good so we sign a month to month contract. That was last seen of sales persons - The modem was delivered by courier and you were on your own. Only assistance was through a call center that take up hours and hours and 4 months later with follow up calls with no success. Emails either don't get answered. Online queries also don't bother to call or solve issues. I'm still waiting for Mweb to port my Landline number to voip. Do you have this service at all or was this a selling gimmick? I'm now without a landline for 4 months due to Mweb not doing anything. Calling them don't help because it is requested an we need to wait for it????? Monthly they want their payment upfront and I will not pay them upfront until I get my full service I signed up for.
