Why Can't I Report A TM Number Being Used For Crimes?

I know T has a lot of tools for avoiding being scammed, but what am I supposed to do when I see a T-Mobile number whose only purpose is to commit crimes?  There appears to be no way to report them and get them shut down. 

To wit: An elderly staff member of mine received one of those classic "you purchased something really expensive from Amazon, call this number to cancel the order" emails.  I looked up the number and it is a T-Mobile number.  If you call it, you get "Amazon's Cancellation Department" which clearly isn't Amazon's Cancellation Department.  I assume 1'000's of these emails were sent out.  

Wouldn't the simplest thing to do, and would be the most benefit to seniors getting this scam, would be to shut down the phone number for violating T's terms of service?  Unfortunately, when I called T's customer service per their abuse page, they kept saying I should just block the email, or add the number to my blocked numbers.

How do I get a clearly criminal number that is requesting inbound calls via email to get shut down by T-Mobile?  Yes, I could file a police report, but it will take days before anything happens.  We could save the elderly from a lot of abuse if there was a faster way…….

FWIW, the number is 850-317-3644. Call it yourself.
