no customer service

I bought a pair of froggies for work on the 25 Nov 2014 for R800. I fitted a nr 5 size and it was to big. On advice of the store manager she orderd a 4 and half size for me. When I tried it on it felt ok but I could feel it was to tight around my feet. The store manager then suggested that we must stretch it for 1 day, so we did. I only went to fetch it on the 27 Nov 2014 that was a Thurday, and put it on and went to work from 9 - 3 then I went back and said the shoes it killing me the manager said we must strech it over the weekend, and I went back to fetch it. On the 2 Dec 2014, again I put it on and went to work in the same building at Edgars. She then told me if it does not work I must bring it back and then they can check if they can replace or send it back so that they can do a check on the fitting of the size for me. I could not wear it for more than 2 hours and I went back.. She said she will send it to the factory and let me know. I send my husband after 2 weeks to go and ask what is happening, the manager was very rude with him and said her boss is not going to refund me and we can take steps. I called customer care without any satisfaction. I never took the shoes home.
