Spree - *****ing Our Money

Bought a jumper in December 2017. Returned same jumper in December and bought a new one as the return would have taken too long so requested that they refund it to my spree account. Which they did. New jumper received and all is well. I try placing an order for something else with my credit and even though the advertising said "Free delivery for R250 or more" they insist on charging me R50 for delivery. So I query this and the agent says "it is because you are in an outline area" I find this strange as I work in Century City, Cape Town so how is this an outline area? No this is false advertising. I then request that they deposit my money back into my account. We are now in MAY and I have not received my refund. I have dealt with an ilhaam who insists my money has been paid back. Just to see that they used an incorrect credit card number to make the refund (I have proof of all of this on email). I had FNB cheque my account, I checked my account and no money was returned. I then log another call with Spree and receive an email "Please rate Mfundo on our service"... uhm reality check you have not even responded again! I have sent some more emails after this and STILL NO RESPONSE. You messed up... How about you pay my R300+ back to me now?
