KFC

I was ordering the wrapsta box and wanted to substitute the drink with something else and add on...I was told I can't then I said it's fine I'll take the meal as it is but now what irritates me is my choice of cold drink was not available but they said it's a must for me to buy a meal like that ....now they want me to add on to buy a buddy

Was helped by Belina and it was not helpful enough for her to help.
