I was blocked once this past summer(?) by someone I never spoke to. I was trying to get an appointment. No idea why. I'm not a serial caller (probably 3 calls in the last 5 months and one of them was about 4 minutes long), I leave positive feedback or no feedback, I don't give anyone a hard time and I'm very pleasant to speak with. The only reason I was upset was because she kept jerking me around with an appointment and having me get in line repeatedly. Completely unprofessional. She should have just told me right off she didn't want to read for me.
If someone feels they aren't a good fit, no problem.
