Garment Sales

I was recently given a present from my Son who lives in Johannesburg which was far too large for me. I went to Truworths to exchange it and was told that the policy is that I must have the purchase slip. I was very disappointed with this as Woolworths, and many other stores allow this exchange without any fuss. I am not going to spend a couple of hundred Rand to have the shirt altered, so guess what - I have lost out on a lovely shirt which I have now given to a friend of mine who was very happy to get it for nothing. I think Truworths should think again re their ridiculous policy as I for one will never again purchase anything for them. I would have thought that the consumer protection act would have come into effect and that Truworths would have to exchange this. I am not asking for cash back, I only wanted to exchange the shirt
