Worse customer service

Herotel is ripping me off, I’ve been paying for my fibre connection at the end of the month or the 1st since inception. This month they suspended my account on the 30th Nov, cool no problem, I paid on the 1st Dec instead of reconnecting they called me and wanting more money. After numerous phone calls and emails they restored connection. Now 10 days later they disconnected my services again claiming I haven’t paid. So I told them to come get their facilities from my house because this is not the first time they are doing this. Now they are telling I should pay R1500 to cancel.
