Order canceled because it cheap.

On the 26 November I ordered a Fila sneaker that I have been eyeing for a whole month waiting for it to be on sale and with my luck it was on sale and I bought it only to receive an email that my order was canceled due to invoice error. I was very disappointed because this is not the first time it is happening, before my order was canceled because I bought things cheap they were R30 and again it was canceled and I was told that there was a *****. Superbalist does not respect their customers. My order number is ***4.
