Terrible customer service and impossible to get hold of people

Been trying to register for a month with payfast a merchant. Followed up so many times, call centre doesn't work, always says no ones available, and on chat I had a guy named Keenan that said he'd help - he sent one email to the same guys I was following up with then he disappeared too despite promising that he'd be my contact person and that I can follow up with him as he'll make sure it happens. It's been 2 weeks and still nothing.
