You have acted in good faith, but good faith is not the issue when you leased the lockers, you presumably signed a contract or agreement or lease for the lockers. Your obligation to pay rent is a contractual obligation and is not affected by your unemployment or other personal difficulties the law does not require the other party to a contract to give up its right to be paid on time because of your situation. They can voluntarily choose to do so--for example, to temporarily suspend or reduce payments--but that is their choice the law does not and cannot force them to to this. And if you default on your obligations and breach that contract by not paying all the rent, they can take whatever steps the contract allows them, which most likely includes auctioning off the contents of the lockers, as well as, for example, suing you for the money you owe.
