Pathetic service from kfc!!!

A disappointing service from KFC Mountain Mill Mall in Worcester! On Thursday evening last week I ordered & paid food on the app only to be told I must come back the following day to collect my order! I asked for the manager to politely explain my case. A lady by the name of Kay Ernest confirmed that she is the manager. I showed her my order & instead she told me I must come back tomorrow to collect my order because as they were closed already. I explained to Kay that I processed the order on the app & it went through & I paid for it online. I got to the restaurant at about 21:09. I showed her the confirmation email I received after placing the order. The email said I must collect the food before 21:30. I would not have gone to the restaurant if I did not receive a confirmation from KFC that I should collect my food. Now I had to go and expose myself to a very disrespectful staff! I showed them my confirmation of the order but still treated me as if I was stupid & as if I was unnecessary. I honestly don't appreciate such a service. Never again! I have reported this to the KFC social media team but have not received any response in this regard. It is Tuesday today but still nothing from KFC!
