Help Please

I've been trying to get help since April 1st. My last chat attempt, I sat there for 2 and a half hours, and no one ever came in.
So I'm hoping someone here can assist me with a few different things. The most urgent, is my bill.

Billing: 1. I'm currently being charged $29.85 for three boxes I returned on March 19th at the UPS store, I have a receipt. I also received an email order confirmation on March 24th, but I never ordered anything, and those same 3 boxes are on there in addition to the three you sent. I returned the old boxes after you guys sent the new X1, and 2 little boxes to us automatically.

2. I also need to lower my overall bill. It's currently - $385.00!

Services: 1. Want to cancel home security.

2. Would also like to find out about the cost of just going with unlimited internet, and home phone.

Orange Cable: It's been there for three years. They ran it in Jan. 2018, and every time we were told someone would be out to bury it, they never came. Last time we were told was March 2020, just before the covid shut down. I then had to care for my husband (cancer), so I was unable to stay on top of it, and trying to schedule around the many doctor appointments was impossible. The box is in my backyard, and they've been out multiple times for the neighbors, and even buried two of their orange cables.
