Returned Fios Equipment but keep getting asked to return

I recently moved and transferred my Fios service to my new home.  I was asked to return the old equipment, which I did using the pre-paid UPS label. That was several weeks ago.  

I keep getting reminders that I need to return my equipment or I will be charged up to $650 per each device.  I have a tracking number that shows it has already been delivered and there is a signature that I can provide.  

From reading the forums, there have been other customers that have encountered the same problem.   Can someone from verizon check this for me?
