Wrong starterpack - Consumer Complaint for PEP STORES

I was at Pep Dealesville, I'm staying on a farm 20km from Dealesville, I drove to pep especially to buy two phones I had no other business in town, I specifically asked for vodacom starterpacks, and when I get home, I saw that he gave me cell C starter packs, so now I have to go back to pep on Monday to exchange the starter packs.
