Who called from 4803270502

Call me daily, sometimes once, sometimes 2-3 times, but leave a voicemail, with no message.

This number calls my cell phone 3 or 4 times a day but never leaves a message, when i call it back it says the person at that extension has not set up their VM. They seem to only call when i am at work (I can not have my cell out then).

This number +1-480-327-0502 from Arizona calls me 2x yesterday and 2x today but never leaves messages. I call back this number and the guy with an india or (indian) accent said welcome to yada yada technical support, my name is yada yada, how may i help you?

too many calls unwanted

They keep calling me after I explicitly asked them to stop calling me and then refused to transfer me to a manager.
