Compliant No Service from Vumatel and CellC

Vumatel no longer has a consumer line so you have to go via your service provider which is ironic since neither understanding the word service. Since September 2021 we have logged a call with CellC asking for the wifi line to be fixed. Vumatel came out a did a temporary fix with a promise to return but months later and after several calls Vumatel finally sent someone 20 December. But we told we must first pay R1725 to rewire but when I said I'm prepared to pay, I was told you have to wait for an email first. The email was going to be sent immediately but no surprise the gentleman disappeared and no email was sent. This is going on from September and I don't know what to do because endless calls to CellC has not worked but we pay on time for this so called service
