bad sevice at store and customer services

i called in for a pick up and go order at kfc parrow mall as i usually do, i was told that that wont happen today as they are busy and the supervisor was very rude to me as well as the manager -nyasha, i have no problem of standing in the line but then i told them i have no time to do that today because im at work and that's why i called in.they usually do offer that service of calling in and picking up your order and i was told that they are not going to do that /serve my in other words they prefer other customers than me,i feel i was treated very badly as i always buy at the store and the service i got was not on for a customer. i then called their customer service line to complain about this and i spoke to a KT Maseli who agreed with the manager and was not interested in what had happened, she was only interested in the incident only after i asked her for her name because i told her that i will be taking the issue further. i am disgusted in the manner that i was treated by the store manager considering that i have my lunch from them everyday. i am further disgusted and dismayed by their customer services in they handled my complaint
