Telkom fibre offer

My dad was called by one of your sales people and was offered your fiber deal. He agreed to it (this was Friday probably mid day or so) and was promised that he’d have time to back everything up, still have WiFi access etc before a new modem was provided etc (not sure on exact terms here) but as of yesterday afternoon some not so clever person at Telkom has already switched him over and now he’s left with no internet access at all. He called the help desk and was told that nothing can be done until maybe Monday, or when someone contacts him. I frustrated for him and I can’t believe how useless this service is!!
