A very bad customer service

I bought a beautiful pair of shoes that I loved so much but unfortunately where they have to be tied up they were uncomfortable on my ankle, now I asked for size5 with the thought that they might be better unfortunately size 5 was too big for me and I asked for a refund but the store manager with a very bad attitude told me that they can’t change those shoes for me because they don’t have any factory fault and that I wore them, so I explained that yes I did wear them hence I only realized then that they are not comfortable on my ankle otherwise I wouldn’t have realized that, the lady kept on telling me that there’s no way she can refund me.

The part that I hated worse was her bad attitude towards me I ended up swearing at her and that’s only when it seemed like she got the messages and then refund me. Such a bad customer service from a store manager she just spoiled my day I so wish Foschini can school her a good customer service because clearly she does not have one, and my concern is that how many customers does she treat like that daily
