My t is fine with phone calls or texts for scheduling, I can also call and leave a message and she'll call me back, doesn't charge for phone calls if they're under 10 minutes. I've used that option maybe 3 times over 4.5 years. I am free to email (I do try not to abuse that) she doesn't always respond. When she does respond, it's usually only 2 or 3 words. The longest email I ever got from her was in response to my question about referring one of my coworkers to her.
