Poor Service and Attitude

On 15th June I went to kfc for order, I placed my order at 17H20 and waited untilnI received it at 15H50. I had to go and complain and a certain gentlemen took my slip and went to the kitchen to prepare for my food . When I requested through Tando to speak to the supervisor , she displayed a negetive attitude as usual. I did not get the supervisor. People are treated badly but this official, she does not treat them as customers. Customers were so agitated by the long waiting time. I humble suggest that Tando must be taken out of front desk or be sent to a customer care training. Secondly the order booking system must be reviewed and be shortened. If there is a shortage of staff they recruit more staff.
