Very bad returns service

Generally I have had great service when ordering online from Makro but this week they have really let me down. I placed an order last week for 2 back packs, a kettle and a gas stove so I can use it on a hike that we are doing this week. 2 out of 4 items were wrong, the stove and a back pack. We are flying out in 2 days so this really doesn't help so I messaged them and all they said was sorry but you have to return it and that will take 2 to 4 days and then order another one to replace it which will take another 2 days. So now I need to go and spend 2 x the amount for a gas stove and 3 x the amount on a back pack to get one before we fly out. They would not help me at all and said sorry, those are the returns conditions and tough. Not very helpful at all.
