I am being bul**** into paying for an installation fee for fibre services that were never activated and now have been listed on the Credit bureau for nonpayment. when querying why I am liable for payment for a service that I never got and had to call you guys day in and day out to activate my service (with no help so whatever from anybody ) more so because i was working from home am told that i was contacted by the Tech mind you this is in mid Feb and have been without service since December ? i logged a request to have this sorted out immediately as this is a big disruption in my life via my score.
