Bad service at KFC Silverton

Very very upset client, with very bad service at KFC Silverton. Gave my order and decided to change it before I can pay, but the lady that help me were very rude. Tell me with an attitude that now I want to change my order after she already put it in, but I have not paid yet. If this is what customer service is then you might close the KFC in silverton. The service is very bad and I will not recommend people to go and buy there. Poor service and poor customer service.
