Customer Service: lets treat them like *********

I work in Hatfield Plaza and had to purchase wine for a company function, I love Spar's quality and service so I try to remain loyal to them. Purchased 24 bottles of wine, the store the cashier advises I am not allowed to remove their trolley from their store, she recommended Box's and she'll get me a plastic Spar trolley that I can use to cross the road to get to my office and car to drop off the wine. 2 boxes were supp****, after that she ignored me so I pushed the trolley out of the shop looking for the red plastic trolley. The Manageress came running out treating me like a ******** as I want to ***** her R5000 trolley, she refuses to assist with another option, I can carry the 24 bottles of wine in the badly wrapped boxes across the street and to my car, when I asked her for another option she told me I could have bought bags, the boxes was a favor they were doing me and if I carry it properly it should not fall. I am outraged to think I support a company just to have to carry 24 boxes because the manageress can't walk with me and take her trolley back or send someone else to help us. From when is it acceptable to treat your LOYAL clients like *********????? NEVER AGAIN!!!
