Charged multiple times for items not purchased

I bought a number of items for my children at the Soviet sale on Saturday 7 February 2015, from the Sandton branch, with my husband and children.<br> <br> The total was R2812.<br> <br> However I always check my slips carefully before throwing them out, and I have discovered a number of items that I never purchased amounting to R692.50, including a \girls branded T pink 6-7"(my daughter is 3 years old) and other items. I was also given a denim jacket that I was not charged for.<br> <br> I would like to know why I was charged for there was such a disaster at the checkout. I will return the denim jacket that I was given accidentally"
