I have not experienced any rude treatment - when I manage to reach someone they are usually professional. HOWEVER, the frustration is that there is no email address, no voice-mail option, and the online booking tool doesn't work and doesn't' allow cancellations. I have been trying to change an appt. due to Covid exp. but the phone has been ringing for 1:27! They are supposed to be open till 8pm but I can't get through. I don't want to be charged if I miss the appointment!
