Most frustrating experience of my life

I pay for a tablet on my line that has now stopped being able to read SIM cards. It is not eligible for an eSIM and we pay monthly insurance on it. I spent 7 hours and no less, and no I’m not exaggerating, 13 people I was transferred to for this problem. Assurant will not cover the replacement and sends me to Xfinity customer care and vice versa. The ending result was to offer for ME TO PAY $50 for a replacement tablet and for me to keep both tablets. Not to mention somehow both Apple TV and hbo got removed or my subscription got cancelled from my account (I can confirm this in my portal AND by attempting to log on and being met with screen to pay to resume subscription) during this 7 hours. Is there a way to get a us based customer support team that can actually solve the problem because I will not continue to pay for a broken tablet and I would like to have my services restored to where they were.
