Hello Leah,
Thank you for reaching out to us. I apologize you are going through this issue. Your current payment method is on the invoice option so your card will not be charged, as it is no longer associated with your account.
Regarding your termination fee, the best I can do for you is waive half of this. It appears the issues you are experiencing are directly related to receiving reduced speeds from running out of data. Since there are no equipment issues, waiving the entire termination fee is not possible. I will private message you the amount you will need to pay after half of the fee is waived, should you decide to cancel.
