Worst customer experience

I ordered my son's school stationery on line. It turned out that Waltons Stationery put up the wrong stationery list by mistake. I under that errors due occur. I have been battling to swop out the wrong stationery for the right one, getting given the run around and all sorts of excuses. I finally received the right stationery after threatening and carrying on. Now I'm waiting to hear back about my refund which I asked about. It's only R100 but to me it's the principle that matters the most. Secomg year I order stationery from Waltons and experience problems. I will no longer give them the benefit of the doubt. Please refund my money and don't expect me to drive in store to get it. The only reason I went to go collect my order in store was because the rep told me he is not comfortable driving to the township as its not safe. I live in the outskirts of the location where there are plenty of Caucasians that work in the area and have never been harmed.
