Block scam calls from leaving voicemail?

A year or so ago, I had basic scam shield from T-Mobile. It only partially worked. The scam shield did block scammers from ringing my phone, but T-Mobile continued to forward these calls to my voicemail which quickly filled up. I had to spend 15 minutes a day deleting robocall voicemails one by one.

My phone was rapidly becoming a nuisance.

Eventually, I had to pay for Scam Shield Premium to stop this forwarding. Yes, if you paid for the Premium Scam Shield, then T-Mobile would no longer forward blocked calls to your voicemail.  

I am not kidding. This actually happened around the winter of 2022. The flood of junk to my voicemail only stopped when I upgraded to Scam Shield Premium.

I do not know if T-Mobile has this nasty behevior but I will find out soon. I have stopped my payments for the "premium" service, and I will find out if my voice mail gets flooded daily with robo junk. Hopefully T-Mobile has stopped this unwanted forwarding of robo calls. At the very least, I would an optional setting so I can instruct T-Mobile to stop this robo call forwarding to voicemail.

Hope T-Mobile has changed this behvior. It is like having locks on your front door, but T-Mobile leaves a a friendly sign for any scammer: FRONT DOOR IS LOCKED.  BACK DOOR IS OPEN> PLEASE COME IN THE BACKDOOR.

And the scammers come in the backdoor. That is ,they come into voicemail.
