Online order disaster

So here is my complaint regarding the online ordering process with KFC where I selected the catering option and then I selected the store closest to me for delivery when the order was paid it said I should check in 2 mins before I collect problem for me having no mode of transport I then phoned the store which said they cannot deliver my order and then **** to me about that if I select catering my order needs to exceed R700 which is utter ******* as I actually redid an order to see if it says that which it didn't then I had to uber to the store and prove my point after multiple phone calls and frustration I paid the uber and proceeded to resolve the issue in-store the same argument continued, I then proceeded to show the store manager that he was wrong which was admitted after I proved to him that their system allowed me to request delivery for this store. I find it ridiculous that it cost me time and money to prove to ill informed staff that The customer was right.
