Multiple trys to get help with my billing issue s

I have had service since July 31 2025. I have not had the same amount for a bill twice!!! It jumps up it goes down,  I have talked to C.S. escalation,  on phone, online and IN THE STORE.  I have been blown off EVERY TIME with out any explanation.  I have found out however I have been being charged for things ie Netflix,  peacock  etc that I actually pay for with each individual company.  I am tell u for the VERY LAST TIME I will be filing a complaint with  FDIC, CFPD, FTC, FCC, BBB, COMCASTCABLE/LEGALDEPT and every platform that will have me. I am 78 yrs old and have been ripped off for the last time
