CHARGED 52850 INSTEAD OF 15990!!! -36860 TOO MUCH

I purchased an ASUS PHONE PAD from TAKEALOT - for R1599,00 and authorized Takealot to debit Discovery Miles totaling 15990. I subsequently discovered that they have debited 52850 miles - 36860 miles too much (equivalent to R3685,00 too much). When I discovered this and queried the gross over charge they rep**** that they will refer to their finance department. I have not heard further and they have failed to refund their gross over-charge. The fact that the day after I placed the order at their SPECIAL LOW price of R1599,00, I learned that another supplier was offering the identical item for R200 (12.5%) LESS than TAKEALOT's SPECIAL OFFER is my loss and I accept that I am bound by my contract with them. I did however assume, wrongly, that the name TAKEALOT was supposed to be in the customers favour, not in theirs in the tune of an overcharge of 330%!!! They certainly TOOKALOT! I do not want a phone call with empty apologies. I WANT MY MILES BACK!
