Worst customer service

I don't know how these guys keep their doors open. Worst customer service. I want to buy something from them so you phone them and they take your details to phone back but never phone back, tried 6 times already. Also tried their Whatsapp line but they don't reply. I can just imagine how difficult it would be to get a refund from them if I battle like this just to buy something that I know they have in stock.
