Groupon dissapoints loyal customers

My wife purchased a portable projector for R 899. on 27/02/2015 and paid R 900. The next day using an ATM,( as we all know coins are not accepted at ATM's ) using the ref no GRPZARSBIT1Q) provided by the supplier. On Monday 02/03/2015 my wife contacted Groupon to confirm payment received, she then learned that the order was cancelled by their system due to over paid account. I called Groupon's office and spoke to Jehaan Manan who also informed me about their system, and I told her, I do not except their explanation and she must find the one that was cancelled. She then emailed my request to myself, [Email Removed] and Bianca Solomons on 02.03.2015 using the subject LATE PAYMENT RECEIVED which is incorrect, our payment was made within the five day payment period. She also informed me telephonically that they were sold out, which is also incorrect, our order was part of the total (297) sold and they would have one extra in there store. Groupon failed to contact us in this regard. I insist on the supplier to supply us with the product as advertised and purchased. <br> This is very, very bad service.<br>
