No feedback in stipulated time

I went to jet Fourways last week Friday and had the worst customer service experience ever! I bought items for my kids but when I got home my kids tried one of the tops and my 4 yr olds top was small. I returned it to jet the Saturday and they refused and said there was a smudge . Very rude in how both the manager and cashier spoke to me. The spot was so small one could not even see it. I have bought items from jet that were dirty before and they didn't have a problem selling it. I received a call from Prenelle in their complaints department on 12 October and was promised feedback by close of business on the same day. Up till today there has been no feedback from Prenelle or anyone from jet. I am a regular client of jet and the Edcon stores and if this is the customer service or the lack of it for a better word is what one gets then I would rather shop at woolies where though the price is more at woolies there is GREAT customer service there . Customers are valued and not treated like a number. I thought I would give jet a chance but from this experience I have learnt the hard way.
