General Revenue Corporation has been calling both my cell and work phone numbers repeatedly during working hours despite me telling them that I can not accept calls at or during work. Today they called a colleague with a different phone number than my own, one that has no ties at all to me, and told her to give me a message. This is harassment and totally inappropriate. I am sending them a registered letter so they have the request in writing, but based on the experiences of other consumers, I do not expect this to be honored. I will send a second if needed, but I am not hopeful.
