Bad business practices and no follow up

I got approached by Henry Zinn around 23 Feb 2018 about VumaTel Fibre in my area. He met me at my house, and as VumaTel had only laid fibre into the cul-de-sac, there was none into our complex. I advised I had OpenServe, and he said he can take it over. I filled in the paperwork and got approved on the 27th of Feb 2018, I said I needed to give a calendar notice to Afrihost. I gave notice and waited for the Login details and then heard NOTHING!!! I tried making contact with Henry Zinn, but he never bothered to reply to my emails or WhatApp messages. My final email and message was to STOP and cancel all migration. as the agreed date and LACK of feedback (login details...etc) You guessed it...STILL NOTHING, pathetic customer service
