Dentist Annoyance

I don't what else to call this but it's a WTF.

Dear Dentist Office:

I know I'm overdue for an appointment. I had to cancel the last one for personal reasons. But, quit calling me every week to remind me!
I will call you.

Me.

Would you consider this B_S? At one time my dentist office called at least 2x a week about rescheduleing my appointment.
