Constant email password resets required on all accounts

I have had this issue for over a year.  My primary account is locked out for the second time in one week because "as Xfinity Security told me, someone overseas tried to login three times unsuccessfully".  In the same week, 2 sub-accounts were also locked and forced to call the 800 number.  In any given month, I will have two accounts locked requiring password changes.  I have to pay the price and call them, despite having a phone number on file which they never contact me on. So my accounts are on the dark web???? No fooling thanks to OPM, Experian, T-Mobile, Verizon, Samsung, Home Depot, name your poison breaches.  My passwords have not been broken.  Xfinity security said I would get a call or text to confirm whether or not I was attempting to login because someone overseas was trying to access my email and I got them only because I threatened to cancel service.  Nothing, nada, zippo from Xfinity.  Well, dammit, I'm not overseas so BLOCK THEM NOT ME or roll out Multi-factor authentication like most SMART companies do. 

What I do notice, is that it always occurs first on android phones before affecting the Linux,  MS,  or IOS systems (14) that are used to access these email accounts.  I am sick of this.  If it happens one more time, I will cancel all of my Xfinity services - PERMANENTLY - and use my free gmail account and go back to DirecTV and Fidium.
