Huibre at cutomer care

I bought 2x Capri pants at Tempo last week. One pants was R449 and if you buy 2 it was R400 I decided to change the one for another colour today. The lady said it was no problem and then when I got to the till, the lady charged me R449 because it was a "new transaction" She could NOT understand that I bought 2 for R400 as per pay slip and I only want to change the colour of one. I then phoned the Cutomer care line and a VERY FRIENDLY and HELPFUL lady by the name Huibre helped me and assured me that it was wrong. She phoned the shop and rectified the problem. THANK YOU HUIBRE!!!!
