N71 5g band FULL BARS fast download and upload and low latency, but this....

I monitor my connections in real time. The 5g band of N71 running at the lower frequency is super great, full signal bars and gives me superb performance. The LTE band will change in an ongoing loop of LTE B2 connecting instantly to 5G N71, then dropping N71 and going to LTE B66 and reconnecting instantly to 5G N71, then dropping my 5G N71 band to allow LTE B71 while searching for a different 5G signal than 5G N71, then cycling back to LTE B2 and instant 5G N71 connection and continuing this loop of cutting my 5G service which does not need disconnected from as it is near perfect and FULL signal. B71 has the same full signal strength as the 5G N71 yet upon either the tower or the gateway or both <according to tech support I just got off the phone with>, the powers that be will not allow my GREAT N71 connection to stay connected at all times. She could not provide me the answer as to why this happens and why I cannot stay on a working 5G signal that is great.  Upon asking if I got my own gateway and committed the band selection to stay on N71 if the signal would hold at all times. She said it would be something to test as  she does not know and informed me there is no higher level of tech support or anyone in the whole company that could help with this and explain why this is going on. Someone does have control of this in Tmobile somewhere. How come I cannot get my internet 5g to stay connected to the 5G band of N71 as no other 5G bands will connect at all when I am receiving a FULL Strength signal of the lower frequency 5G band N71 when it goes through this cycle loop, causing severe latency issues and hindering me from staying connected to a 5G signal which is working flawlessly as I do pay my bill and should be able to stay on a near perfect 5G signal on band N71? I lose my perfectly working 5G internet due to the releasing of the signal as either the tower, gateway or BOTH are working against this.Support can offer NO ANSWER at all….who do I talk to so that I can get the service I pay for and is proven to be working flawlessly when the service provided by TMOBILE is being completely DUMB sand STUPid for a lack of better words? I pay for 5G please let me use the signal that is in my house coming to my gateway at the best connection I have ever had in my residence on the N71 5G band. My  internet is advertised as Tmobile 5G home internet, says it on the bill. Am I not being denied the service I pay for?  for whatever reason? 5G band N71 works flawlessly and the technology they are using or the code which is running the tower and/or gateway is denying me of great 5G internet and Tmobile is not providing the working 5G N71 signal to do the job I am paying them for. Gracias.
