Unfair practice- Customer refund or exchange declined

I'm very disappointing and hurt that I bought my sister who lives in limpopo jeans and when she tried them on,they were small and now I'm told by the woolies in fourways, that I can't return them or even get a voucher to buy something else with that value as 60 days has passed- apparently their new policy! in these tough financial times. I am now supposed to lose out on R799 on jeans that have not been worn and still have tags! Woolies, you can do better than this!! Pls dont tell me about sending an email to customer service. That is a total non-existant service full of *********** consultants that cant resolve anything! Been sending emails from the 29thof April till today, i have no resolution, only a ref number (***). Great right?? This says a lot about a company that prides themselves with quality...one would expect the same when it gets to customer query/ complaints resolution! @Woolworths_sa, I await a response and proposal of way forward before I take this up with higher retail industry regulators on unfair practice. Thus deserves a no star at all due to the number of energy I as a customer has to use for this whilst you could not be bothered!
