Bafute Carpet Cleaners

i contracted Bafute Cleaning Services to clean my carpets/upholstery. On the day of "service", I was messaged to say they would not proceed until they received a proof of payment. Never discussed before this. I said I would do an EFT before the team left me. I asked whether they pay for food at a restaurant before they've eaten it, or paid for a car service before the job is done? Anyway, ended up arguing about this, only to be told, that in fact, they wouldn't be coming anyway because it was going to rain (which it didn't). Just as well I hadn't paid! Dodgy - to be avoided - carpet cleaners are a dime a dozen
