Wrong order by Clicks Online

I ordered 2x Pampers 44x nappies no 6 jumbo packs. Order #180 ********** . I received 2x Pampera 40x pants no 6. I had to take the wrong order because we needed the nappies, but I am really not happy and feel cheated. I paid R369.90 for 88 nappies, but received only R80. Anyone with a baby will tell you that 8 nappies make a difference. Clicks owes me R33.62
