Still awaiting refund 2 weeks later.

Over 2 weeks ago I ordered a keyboard online. It was paid for in full. Only after the transaction was completed, I was told that they didn't have the model in stock. I asked for an immediate refund which I have not yet received. I was to understand it would take maximum ten working days which was frustrating in itself and I was never offered much by way of apology or customer care. No follow up or feedback has been volunteered and I've had to initiate all follow ups. Just a disappointing process and attitude. The inconvenience could have been mitigated by a simple curtesy call or basic customer care. Casio should also make better efforts to keep their website updated to reflect accurate availability.
