DROP CALLS EVERY DAY

[IDES74]

I purchased a home 1 1/2 years ago in SMITHFIELD RI. I immediately started dropping calls. I called Verizon and spent hours, which turned into days on the phone with this problem. We went thru everything… shut off phone, turn off Wi-Fi, reset phones, etc .. they even sent me an extender.  NOTHING I MEAN NOTHING WORKED !! They basically said 🤷🏻‍♀️ We don’t know. I would call verizon cellular and they would blame FIOS … and FIOS would blame Cellular.
We have 2 brand new 13 plus iPhones and 2 brand new X plus iPhones in the home. And they still drop 3-4 times on each CALL!!  While I was on the phone with customer service for days it would disconnect me numerous times and they would never call me back!! IT WAS DRIVE CRAZY! 

I am at the point I just don’t know what to do.  
We even bought other extenders called EERO’s …. And they haven’t helped.

can anyone help????? PLEASE PLEASE PLEASE 

Desperate for help
