********** to small businesses

They are so ***********, have false adverti*****t and are **********ly charging small businesses knowing we can't really fight back. The advert says it charges 2.95% but saw myself paying way more than that percentage only to be told it was payments after vat. Which are hidden from us. They gave me an option to pay for the machine monthly, weekly or once off. I chose the once off option but ended up seeing unauthorized debits of R64 from my account which I ended up disputing. Now I'm getting emails from credit bureau that I owe them for desputing debits which I had payed already for the machine in cash and didn't authorize. Please be careful when they say it's cheap. Its usual too good to be true. I feel ****** and need to inform people to reconsider before making the same mistake.
