calls from jail

I been having the same problems. First that call Securus telling them that the calls were not coming through after 6 PM for some reason they told me had to do with T-Mobile so I called T-Mobile T-Mobile did a diagnostic check did everything everything came out good so they forwarded me to their senior technician to see if they can figure it out Unfortunately they were unable to figure it out so they transfer me to Apple Apple did a diagnostic and also did a screen sharing to make sure all of my settings for spam calling was off the Wi-Fi calling was off so everything came out good on there so I called T-Mobile again. I told him listen I'm not getting any calls past to talk and now when I get regular calls from iPhones, it comes up as FaceTime audio  And I wasn't receiving calls for some reason past 6 PM. It was like I had only eight hours to use my phone. I was advised to do a network reset so I did that after that it was still not working so I would advise delete all my focus  Options I did that second option was transfer all my files and pictures to a computer or a laptop and do a factory reset and guess what it still didn't work. So the next day I said you know what maybe the phone so I went to T-Mobile went and purchased the whole brand new phone  And it still doesn't work so I'm unable to speak to my husband because the calls are not coming through and everyone is blaming everyone is blaming T-Mobile T-Mobile is blaming securest then T-Mobile is also blaming Apple the software update thing. No one knows what's going on the problem is I still cannot receive calls past 6 PM so I need someone to give me an answer on what to do because I just spent over $500 that didn't need to be spent. So there's something wrong and someone needs to fix it.
