Birkenstock bashafrica

I purchased a pair of sandals that were on sale from bashafrica.com and used the sizing guide on their website to make sure that I was ordering the correct size. I received the sandals 12 days later and they did not fit. I sent an email asking if they could be exchanged for a size that would fit but go no response. I called Jade Herrington at bashafrica and explained the issue with their sizing guide. She offered to replace the shoes with the correct size. I heard nothing for 7 days and after another none response via email, I called her and she said she would follow up and get back to me. Later that day I got a response via email from Sherezaan Petersen at bashafrica telling me it was a sale item and there would be no exchange (because they didn't have stock) or refund. I checked their website and they had replaced the previous sizing guide with a corrected version. So, I bought a pair of shoes I can't wear from a very unresponsive company that does not put the customer first. I doubt the ethics of this business - good product but ***** agent.
