No Response from Customer Sevice

I tried to place an order on Sunday night the 25th at plus minus 10 for an item on sale, not realizing the sale is closing at 10. I was under the impression it was closing at midnight. By the time I had changed the delivery address, as we are on holiday in Cape Town, the price had changed. I sent an e-mail to customer service, including a print screen, but they did not contact me. I phoned the helpline on Monday and was then told that the sale ended at exactly 10 and that was that. I sent a second e-mail, attaching a print screen that shows by 10.05 I could not get the item, but once again, no feedback. I love Spree but find the fact that my e-mails get ignored not acceptable. The query number is 233365
