55 and older for 2 people on plan. Why is my plan 79.66 a month?

My bill for essentials 55 is 77.06 here in Florida.

it went up $5 a line because I would not switch to a less secure payment option. I use a credit card and they want me to use a debit card, which is less secure. I may be switching to Visible for $50 for a total of 2 lines ($25 for each line) for the same coverage, they take credit cards.
