Headoffice don't trust their staff,why should we?!

In summary I purchased a product from Partners and tried to get a refund. (What a mission!!)The staff at the store first needs to get authorization from headoffice to process the refund, then headoffice will do an Eft to me. What makes it worse, is that Head office does not work on weekends, therefore the store won't accept my product, which means I need to drag myself to one of their stores in the week ( after a full day at work). It's a quick and simple process for partners to take our money, but makes it really difficult to refund our money. Furthermore it's clear that headoffice does not trust their staff at the stores, so why should customers trust their staff?? It is appalling!!
