Querying service and policies

I went to Mall Africa to exchange items that were bought by my gf for me. The problem (which is not usually a problem @woolies is that I didn't have a receipt) is that I don't have a receipt. I took what I want trying to get an exchange but I was told that the policy has changed. My problem is that on the back of the receipt it still says the Samething but apparently it has been updated. I went through your refund and exchange policy and nothing has been updated. I used my petrol and my time to go do an exchange only because I know you guys do it. I was told to call my GF who is overseas on a business trip to find out where and when she bought the stuff. The last time I checked woolworths is one company it doesn't matter the branch. I'm sitting here with clothes I don't want because you guys changed your policy and don't update us as loyal customers. Please advise what to do if nothing can be done I can just go drop these clothes at your store and advise my family, employees and the people I laise with to boycott Woolies because yesterday I saw you guys refunding a white lady without a receipt or a rewards/my school card. Your service is really starting to lose its plot.
