No refund two weeks later!

I placed an online order for building material on their website. The order went through and I was able to pay for it despite the fact that they do not deliver building material outside of Gauteng. I was then informed that they will refund me as their system should not have allowed me to proceed with the order as delivery would not be possible. I was told that the refund takes 7 to 10 working days. I am still waiting for my refund two weeks later and have had to halt the building process as a result. I am extremely disappointed with this store. Their refund process is terrible to say the least! Do not purchase from them.
