Missed lead services

I have canceled my Vodacom to join Vox telecom as the sales person was so great to sell this to me , it have been 2 months later no internet was fitted , no one come out or have I even been informed about anything. If I don’t call or what’s app the sales person I don’t get a reply to know what’s going on . I been at home due to what we going true an have to work from home , no I have requested to cancel so I can go to a different network to work from home an I get a R3000 bill from vox to pay for no service or even made the effort to come out to my house . Is this fair ??? This have been the worst service I have ever received . Don’t ever use this wi-fi service VOX TELECOM ….
