Pathetic Service

I ordered 2 Biltong Dryers online(8/12/2015). I paid a extra fee for delivery to take place in 2-3 workings days. On the 10th I called to make sure that the delivery will take place on the 11th cause it is the 3rd working day. After I called 5 times I eventually got in contact with some one that can assist me and I was promised that the delivery will take place on the 11th before one o'clock. And nothing was delivered. I called the shop online number again and the only answer I got is that the delivery will only take place on Monday that is the 4th working day. I asked for a refund cause I am going on holiday and will not be able to receive the package. I was again promised that the refund will take 2-3 working days. But as to date(19/12/2015) I did not receive my refund. When I call I dont get someone that can tell me when I will receive my refund. I am still waiting for my email for proof of refund as promised. This is really pathetic!!! The call centre are always busy. Ieft my number and name 2 times for someone to<br> call me back and I am still waiting.
