why do Securus calls not come through?

I'm having the same problem I've been bounced between Tmobile and the security technologies. Customer Care both have done extensive inquiries into it and it's looking more like it's Tmobile 's fault. They're blocking almost all phone calls from Tmobile . Customers secure says 80% of their daily calls from Tmobile customers with the same complaint, I've reset every setting possible. I've talked to customer support multiple times. I'm currently talking to them now very colorfully worded and angry and that's barely getting me up to where I need to go. They told me it would be seven days before they get back to me as to why it's happening. Why pay all this money for them to without consent or knowledge block the services that were paying for on top of paying to have the calls from the inmate from Securus ?? They sure are quick to shut off your service if you're a day or so late, but it's gonna take weeks??? which I have been calling about this for literally three weeks now.this is wrong and can't be legal if someone knows of a national lawsuit or something let me know 5057300023 I'd like to join . .
