Cape Union Mart bad Customer Service

I bought online from Cape Union Mart , they delivered the wrong size, I phoned and email them and the lady on the phone said they will collect the wrong shirt and then deliver the correct size. Week later, I had to phone again. The answer the emails 2 days later. Then this morning they said thet do not have stock. Online there is still 2 available in the correct size. I will never buy anything from them again. They do not care about the customers. I never experience such bad customer service before, for such an expensive place you will think they will be more professional.
