Return Policy at the discretion of each store

Bought a guess bag online, did not like the size of the bag. I took the bag the next day to Woolworths Westwood Durban to return with the tax invoice and delivery note, the packaging was intact. At the returns department the cashier and manager advised the store does not stock brands i need to do the return at another Woolworths store that stocks brands. I advised this is an inconvenience as this was not close to me and i do not frequent those stores. When I contacted Woolworths online shop and customer service I was sent the returns policy and, on the policy, it did not state return on brands can be done only on stores that stocks. I was also told a few times it is discretion of the store, which is a ******, ***ist statement to be made, as what does that mean only if u male or a certain race group the store will decide to process your return. Woolworths you need to get your policy in order and stop responding with nonsense to customers who give you quite a bit of business.
