Porting number issue

The call is also getting disconnected from time to time so I keep on dialing tmobile number. We are very unhappy with this first tmobile experience I literally want to go back to my old carrier. Please look into this today. We have three numbers we needed to port but only two got ported but with different phone numbers. Also, my number is still not active on my phone as I specified to the agent that there is literally no sim slot on iphone14 models and before it got resolved, the call ended. I do not have a phone that can be reached right now because of this.
