Undisclosed deposit charge of $125

Nowhere in the checkout process when i was signing up for the 300Mbps for $40/mo was there any indication of a deposit fee and in the confirmation page after signing up it also had due today listed as 0.00$ with the text under it saying "This includes charges like one-time deposits, device payments, and taxes". So why in my email is it saying I paid a 125$ deposit, if the text is saying the due today is where one time deposits would be if there were any?
