Makro has the worst staff under the sun

I am a long time purchaser at Makro. The staff that are supposed to take orders do not bother to return their messages and don't answer emails. Namely Dan. When I called in again, I was told to phone back in 20 minutes by Patrick. I explained that I wanted to place an order now as I have been trying to place my order for the past week. Patrick said leave a message for Dan. I told him that Dan does not return his messages. He then proceeded to tell me to call back in 20 minutes and put the phone down on me. Now ordinarily, I would approach their customer service centre but guess what I did that previously and was treated like ******* by their call centre. Who takes ownership for all the ******* employees at Makro?
