Please refund my eBucks

On 13 March I placed order *** on your website. It was paid in part in eBucks. Because your website would not allow me to pay the rest of the money (the pin code page kept timing out, and when I tried to pay with EFT it said FNB was unavailable) I cancelled the order. The website has no option to cancel it, so I had to e-mail. Robin was in contact saying the order had been cancelled, but my eBucks were never refunded. When I asked Robin what the ETA was on my eBuck refund she merely said \We have forwarded to the relevant department". My eBucks have still not been refunded. It is not an insignificant amount (nearly R900) and I would like it back please."""
