Extremely poor service from Makro

I ordered a dstv decoder on line 20 days ago. Order no MAK ********** . After not receiving it after more than a week I drove to the Germiston store and was told that ther are no stock and I will be given a refund. I was promised the refund will reflect in my account within 2 to 5 days, its been 11 days now. I have sent emails to the person I spoke to and he does not reply to my emails. I even wrote a hellopeter coment and makro came back to me that they will look into the matter, well guess what, still waiting for that too. I find the service from Makro extremely poor, promices get made, and not kept, they don’t even have the decency to reply to emails, and as for their online phine numer, phoned that twice, was promised they will get back to me, and still waiting for that too, and I still don’t have the money that they owe me.
