If you signed a contract for $44.99, that's all they can charge you--though you need to review the contract and the invoice/bill carefully, to see if there were other legitimate charges (e.g. taxes; service or processing charge) which you were not taking into account. If after that, they are still overcharging you, you *may* be able to get out of the agreement IF they do not correct matters (and refund or credit any overpayment) once you bring it to their attention. A fairly small billing error (less than $12) will not invalidate a 36-month contract--it is not sufficiently "material" or important--unless the company refuses to correct it.
