Forced to enter additional digits after dialing an international call

I am seriously considering switching four phone and iPad lines due to the additional digit entry.  T-mobile has a way for customers to block their accounts from making international calls if they choose not to use this feature.  In case T-mobile forgot, I am paying for this service.  I don't want, need, nor asked to have additional fraud prevention added to my phone.  I consistently call the same international numbers and I consistently have to enter the two digits.  This is unsafe while dialing with handsfree in my car.  I either have to pick up my phone, unlock, and enter the code or I have to go through the menus in my car.  Neither are safe while driving.
I asked T-mobile to discount my bill due to the additional time I have to waste every week adding in their new codes and they declined.  I spent about an hour on the phone arguing to have this service taken off my line, which was also declined.  The girl was very rude and transferred me to tech support with no information so I had to reverify my entire account with the second guy.

This is very clearly a T-mobile problem with fraudulent calls but instead of T-mobile handling it themselves, they make their customers problem. 

I'd really be bummed to see you leave over this policy. I understand that it takes a few more seconds to make a call and that you don't agree with how it's set-up. Trust me, the feedback has been passed along to be able to remove this feature at the account owner's request.

Is yours a business account or a family type account?

Hi- take a look at the reply from the TMO rep above where she says "This is a feature that cannot be disabled at this time but the request for the option has been forwarded.".

What makes you think then that I can call C/S and get it disabled? I did call them and they said the same thing that Amada said above...so if you know any secrets I'd truly appreciate it.

Thanks!
