Xfinity charging me for ghost data usage

@XfinityKei​ I have tried three times to get this straightened out, and the only answer I get is that is is a good charge.  I asked a few times what was causing this charge and all the operator wanted to do was transfer me to someone lese.  By that time I was upset because I felt like I was getting no where and the operator, or agent, was not listening to what I was trying to tell her.  I have now been forced to either go to unlimited Data or change cell companies.  I changed to unlimited, but I am still thinking of trying someone else.  I have just discovered Esim cards and my phone is capable of running both a physical sim card and an esim at the same time.  I even found a 7 day free company for a trial that can use an esim.  Still deciding what to do.
