Closing Account.....???

My contract expired two 3 months ago almost i didn't realize it so my charge seem to gone up more since then i was looking at triple play deals i seen one for 69.00 but when go build a bundle online it says 124.99

Just feel like my bill to high recently keeps going up... for some reason

is it also possible switch form triple to double play if contact up? if not how do i close the account online?
