So I bid on 3 paintings and won all three. I go to pay, and I get declined. The site advises me to contact my credit card. I contact my credit card and they tell that they didn't get any request for approval. I email Catawiki and explain the situation. According to their website they are suppose to respond within 2 business days. After three business days, I get no answer, but I do get a nasty email saying I late with my payment. In reality, according to their site I have three business days to pay. I call them and explain the situation and complain about receiving the nasty email and not receiving an answer to my email. The answers I get are the they have no control over the emails that their computer sends out and that they can't always get through all the emails they get in a timely fashion. The representative said that she will escalate my issues to financing department and get back to me with a solution. After another three days of waiting, and not getting any answers, I tried my credit card again and this time was successful.
