Disgusting customer service

Take alot sucks... they falsely advertised a product on their website. I the returned it on RRN 8fba 6585. I was told that my account would be credited with the said amount, so if I purchased anything, it would be set against it. This was to prevent a double purchase on my credit card. I was also advised that I could do a COD in the interim and that they will sort it out if an order is placed. I got an email stating that my account was credited with the amount. Upon trying to do a transaction, I discovered that my account had not been credited. I called and spoke to Jay. In a very patronising tone, he says that it's not his problem if I can't use my credit card. I asked to speak to his manager. He puts me on hold and comes back to say tgat his manager is not available, but sent a message about how a preferred method of reimbur*****t was used. I then asked how did he get a managers response, but refused to let a client speak to them, I was informed that Zahruh doesn't speak to clients...
