Shocking after sales service

I have ordered numerous sneakers from Converse South Africa in the past 2 years but for my latest order (Order Number 2442) they sent me the incorrect colour shoes. I have emailed their customer care department about 5 times now already without a hint of them responding to my request that they arrange an exchange to correct my order. I have even tried phoning their customer care number which also just goes unanswered. You would think that they would check your purchase history to see how much you have supported their brand in the past and that they would go out of their way to keep you as a regular customer but they obviously just don't care. I think the only way to get a response out of Converse South Africa is to name and shame them on every available social network platform such as Facebook, Instagram, TikTok, etc. Whoever is in charge of their customer service department needs to be replaced ASAP
