Rubbish customer service. I participated in their rewards program but wasn't able to withdraw my Amazon vouchers (only £16 but would have been nice to have since my friends signed up basically just for that reason). I reported the problem and someone responded asking for screenshots. Then they just closed the chat. Regardless of how free those vouchers were, I was advertised and promised them, and the agents took over a week just to respond and close my chat once I stopped checking. Feels scammy
