Online order can only be exchanged in-store (I HATE MAKRO)

This is one of the most frustrating experiences to have to encounter with a store that purports to be all about customer care. I am more upset with myself with trusting them again. Not only was the paint colour wrong (we wanted white) when we did the order and wanted to do the exchange we were told to come IN-STORE, WHEN WE ORDERED ONLINE. Their delivery costs is built in so now we have to come in store to exchange. It gets even worse, we only have +-3 days left to come in-store AFTER ORDERING ONLINE. WHATS THE USE AND POINT if a simple exchange cant be done as the delivery was. So now I am out of pocket of close to a 1000 rand, no viable means to get to the store in time and Makro is laughing all the way to the bank with my money. I hate this store I really do. I will block ads, the site and everything. I loathe that I did this to myself again by trusting them. I await a generic reply, as nothing will come of this, as before. Surprise, Surprise.
