No customer service

Bought one of their new glass mugs to sublimate on almost two weeks ago. They gave incorrect pressing instructions {not the first time} and I then had to fork out more money to purchase something else for a client. I have been promised a call for the last week and a half and nothing. The staff gives me the same sob story every single time. It is unfair to spend money on products with incorrect information every time. How are small businesses supposed to survive? Their whatsapp line reads my messages and doesn't bother responding. Cape Town office blames Jhb HQ. Deeply disappointed on how they treat their clients.
