National Tire & Battery [NTB]

I am so pissed now I could spit bullets. All I needed was a slow leaking tire fixed. I called first and they said they can do it yesterday 12.12, 2020 and well they did not. They said come in the next morning so I drove there and it still was not fixed and they said it might be sitting there another day. WTF why in the hell did they say bring it in, in the first place. I will never ever use those people again, but I am still down a car for the rest of the weekend. WTF I hope they go broke.
I tried complaining on their company website and "they are having technical difficulties", so I could not leave a voicemail and there is no way to email them. How convenient for them.
