A term contract is a type of Contract with a specific start date and end date, and which requires a commitment until the end date. A term contract comes with an initial large term deposit added to the bill of the first month of the contract. If the customer cancels the contract early, the deposit is forfeited. If the contract is carried to term, the customer gets back the term deposit. That is$,$ if the contract gets cancelled after the end date of the contract, then the term deposit is returned to the customer, minus that month's cost.

The perks of the term contract consist of:

having a lower monthly cost than a month$-$to$-$month contract

lower calling rates, and

a number of free minutes included each month, which refresh when a new month starts. Free minutes are used up first, so the customer only gets billed for minutes of voice time once the freebies have been used up$.$

To prepare, have a look over the TERM$\_$DEPOSIT fee defined in contract.py$,$ as well as the corresponding rate per minute of voice time.

You can assume that the bill is paid on time ea
