Bad service

I was at the Greenstone Foschini on Saturday and saw a top I liked but did not have a size and the lady was helpful to inform me which store to find it. But decided that I will make the call on Monday to find the t-shirt since it was hectic in the store. To find out that today when I call the Fourways branch I just told them am looking for a top and when I was about to give them a code number she just put me on hold for 13:15 seconds without anyone getting back to me. I spend that time hearing them laughing and talking with no assistant. this was unprofessional and unnecessary they should have said they cant help or take my numbers if they were so busy. I will never ever again do my shopping at Fourways.
