Apollo.io Customer Service Representative interview questions

I applied as a technical support but they put me in customer service I was interviewed by the guy and he keeps looking at the other side of him which made me bothered. However, he moved me forward to role-playing but he only sent an invitation for scheduling. I thought the role-playing is just about the “pretend calls” but you need to navigate their software and the woman who interviewed me was disappointed cause I can’t navigate it. I told her that I don’t know how and she said it’s alright ( pretty but you know she ain’t kind) and I told her I don’t know and haven’t navigated your page and that’s the time she said she will talk to the first guy who interviewed me right after that horrible interview. Almost a week has passed, no email from the guy. Now I have received an email from him saying they won’t move forward with my application. If you don’t want to waste your time, don’t apply here.

Everything was properly explained at first. . HR scheduled a second interview only to cancel 30 mins before the interview because they had a "sudden" change of process in hiring for a customer service position.
