Whataburger complaint: Rude employees and managers, terrible customer service

I never go to this location although I live 3 minutes away because they are always so rude to customers. I figured I would give it another chance as I go here maybe twice a year hoping there’d be better management.
Well no, the service remains terrible. The employees are so rude to customers.
I called to order to ask if I could order through the phone because the whataburger app was not working. They answer the phone and I just hear a conversation between employees laughing. I’m on the phone for about 30 seconds just saying hello, hello to see if anybody would answer. They had me on speaker and they finally say “whataburger” I asked if I could order through the phone. The girl on the phone is again talking to an employee laughing and I again have to say “hello?” She sighs in annoyance and says “Ughhhh” as she picks up the phone rather than having me on speaker.
She says with an attitude, “Uh yeah but you have to come pay for it at the window”
I say “Ok but there’s not need to be so rude, and hang up.
I decided not to order from this horrible location and went to another.
I will have to keep complaining until something changes.
