No delivery

I ordered the so called free products and paid for the shipping. I was enrolled onto the program when I hadn't even received my pills. I called to complain and was told that I have two options to either pay half of what the company had debited me which was +-R675 and still get all my pills or wait for the delivery and ship it back at my own expense and get a full refund, this was in September. So I opted for the 2nd option, I got half of my money back after calling for the second time to complain about my money nearly taking two months to be refunded. I have now called the call centre three times this week to request for my money back seeing as I never got my pills, I was advised to go to my post office with an order number to trace it. Really!!! The lady looked through all her parcels and my product was not there, I have requested for a tracking number and they keep referring back to my order number. And that Alex call centre representative is either an android, can't spell or is punking me. I just spent money on calling these people who seem to have no clue what they are talking about. Now I just want my money back. If you cannot keep your end of the contract then your in breach, and you can't tell me that you can't give me a tracking number because parcels get send to different parts of the world, that's not my problem and what kind of company are you running where you cannot trace your products ?
