Return

On 22/8/15 I bought two blouses, (R129.99 each) one was size medium and the other one was size XXL. My sister in Bloemfontein said that I should rather take a XL for her and I went to Mr Price in Gateway to return the one and take a smaller one. On 28/8/15 I went to MR Price in Gateway to return the one blouse and took a smaller one. I also paid R500. The cashier asked if he could keep the slip with the return and I said yes. I then bought the smaller blouse and another blouse (R119.99) and I returned the blouse for R119.99 to Mr Price La Lucia Mall on 29/8/15. Last week when I received my bill, I see that the XXL blouse does not show as a return but it shows that I bought 3 blouses. Now I do not have the slip to say that I returned it as the cashier kept it. I think that if Mr Price goes through their documents for the Saturday morning at 09:05 they will see that the cashier make a mistake and never returned the one blouse.
