Bad Customer service Cape Town Tread + Miller

I am shocked at how the Tread+ Miller customer service in Cape Town Behave. I have lodged a query about a purchase I made yesterday online and it looks like there's incorrect information online or should I say misleading information. I bought shoes yesterday and specifically said I will collect them from the shop in PTA either today or today because I was buying them for tomorrow's function, now I get a confirmation for a courier delivery which I don't know anything about. I call the customer and the lady I spoke tells me it will take three to four days to deliver your shoes and I said to her that's not what was confirmed with me I have confirmation that I will collect from PTA why must I wait for after the function I might as well get my money back she asked me for that confirmation which I had to send and now they are not taking my calls which is really disappointing. They are not answering their my calls I want my money back to go and buy somewhere els.
