Called them back and said it was Verizon Wireless

I received a call from 407-583-6341. The call is from Verizon. They don't leave a message, just call continuously, and on many of their different numbers. I have had my cell phone for approximately 23 years (same number, same carrier), and have NEVER, please allow me to repeat, NEVER used Verizon as a carrier for my cell phone services.
