It might depend on the exact wording of the letter, but it sounds like they gave you 60 days notice of an increase in your rent. Usually that sort of letter includes a statement that if you choose not to renew, they will charge the new rate plus the month to month fee. They can do that without you signing a new lease at the higher price.
