returning clothes that i bought but could not fit

I recently bought items on laybye however when I got home I changed my mind on 3 items that I bought and re<br> turned them back to Ackerman's Rossetenville however once I got there a lady called Zanele asked me where was my slip I then advised her that I no longer have the laybye slip she then advised that if I do not have the slip then they cannot assist me and because I do not have the debit card that I paid with and that the items had now gone on sale so they will only exchange them on the current sale amount and not the amount that I paid for them am. I then started getting very irate then a lady called Thandi and Mmathapelo( I think that's her name but she's the manager there) came and explained to me very politely even though I was irate of why they need the bank card that I swiped with (***** purposes) from just speaking to these 2 lady's I knew that I was going to get assisted! They were calm and understood where I was coming from! They know the importance of good customer service! The whole staff at Rossetenville are always very helpful and I would like to Thank each and every one of them and especially to the two lady's! Well done guys!! That was excellent customer servic
