FirstName/FamilyName FUBAR

Every written comm I receive from Telus addresses me like so:

"Hello, FamiliyName"

Where I come from, this manner of addressing is impolite at best; acceptable formats being either

Hello, Mr/Mrs/Ms FamiliyName 

OR

Hello, FirstName

I have reported this at least a dozen times to no avail. It so happens that my First Name sounds like a Family Name and maybe some brain-dead algorythm is twisting things.
