Pathetic service

What a load of parhetic people, after I cancelled my contract, in 2023, no further invoices received, today I received a threatening letter of demand, for an outstanding balance. Lawyers threatened me that I had to pay for the letter of demand, furthermore threats of judgement being obtained against me that I will be held liable for. Something is seriously wrong with this companies billing system. I would not recommend anyone to make use of their services. Obviously totally unaware of the stipulations in the national credit act!
