Not receiving texts from Verizon carriers!

I am going through this right now.  I have been going on with this since this summer.  I cannot deal with it any longer.  I have been into tmobile and got the worst service ever.  Tmobile told me to tall verizon, verizon told me to call apple, apple told me to call tmobile.  It is literally the worst thing.  I have had multiple escalation tickets.  The last resolution was that  I call verizon and talk to them. And guess what they told me to call tmobile.  I took my card off of  auto pay, I am not paying my bill.  Or I am going to give them back and tell tmobile to pound salt.  I do refuse to get a new phone number  this should not be a me problem and me doing the middle man work.  I cannot text my brother, my husband, or my mother.  This has to be the biggest in convenience ever.  I use to be able to talk to people through group chats but now It is not working.  IF anyone has any other suggestions please for the love of God let me know.
