Crisp Fiber nonsense service!

Absolute the worst service in my entire life, I moved into a complex and was using Metrofibre at that point and because I needed to cut down on expenses, MF was a bit expensive but good service then Crisp got a tender into the same complex at a cheaper rate and I signed up for 10/10 deal which never connected so upgraded it the very next few days of NO service to 25/25 which was even worse! An invoice was sent and I responded to the invoice asking for an explanation as to why I don’t have service, the most speed I got on my meter was 0.2kb/00 and I sent screenshots of the speeds to no one’s response! Fast track I get an Email from Barend Prinsloo threatening to hand me over if I don’t pay invoices and he shows me snippets of the data I apparently used since connection despite all the efforts to get clarity on why I never got service yet being charged. I had to find other ways of getting internet in my house for work as crisp was just not coming to the party. Worst service rendered EVER!
