KETO ******** / **********!!!

I ordered a Keto Advanced Fat Burner on the 27th of January. The advert showed a price of R579 but when I made the payment they deducted R3511. They emailed me to confirm the order and gave a delivery turn around time of 14-21 days. I emailed them to cancel the order on the 10th Feb but they never rep****. They never delivered the product either and I have not heard anything since then. I WANT MY MONEY BACK!!!!
