Terrible service

been waiting for refund 3 weeks. First ordered order number 352841 then they were sending it, then they cancelled it as there was no stock. I had to get a credit to order something else. then ordered order number 357102, they apparently were sending it, then when I asked where my order, they said oh there no stock. I phoned their offices 15 Feb and requested refund via email the week before, so followed up with Michelle Mathebe at call centre Tel *** and she told me that there were 3 more working days left in which the money should be paid back to me by Tues 20 Feb. I emailed Tuesday 20 Feb and they are now saying by the end of the week. This is not acceptable. Asked for them to escalate, phoned and waiting on phone 14 minutes after which they cut me off. Still no refund. Terrible service!!!!!!!
