Videotron is sending emails like spam !!!

Can you, Videotron stop sending same emails for 6 times? I thought Videotron have pro people working, but I see just kids. When you send an email regarding billing it is enough one time if is the same thing that you want to transmit, do not send 6 times. Hire proffesionals to do the job if you're not capable !!! But I guess your criteria to hire is politically....Shame...
