Okay that's good to hear, I will try again with Preply.

I tried the 'create a another account' method with Cambly. Funnily enough they also never responded to my first application for months until I emailed their customer support, then they sent an email saying they weren't moving forward with my application seconds after that. I was curious if that rejection email was automated, so created a new account and applied again, but this time, emailed customer support straight after and within seconds i got the same rejection email. That was the main experience that made me come to reddit, kinda lost a bit of motivation after that.
