still have not been re-payed and still been charged to much

user_2quw55 Thank you so much for reaching out for help with your billing concerns. I definitely understand reaching out anytime your bill is not what you expect, and I appreciate the chance to help. For the $25.00 fee, if your bank returned or refused a payment, that would be due to an error on your bank's end, not ours, so the fee would be valid. As for rental fees on devices, these are all generated by billing codes on the account. If a device is not returned, even if not in use, you will be billed till a return is processed when that code is removed. I would be happy to help look into the rental charges for you, but any fee for a returned payment cannot be able to be adjusted since that was not on our end, but your bank that generated that fee. 

If you could send our team a direct message with your full name, the name listed on the account (if different), and the service address associated with your account, I'd be more than happy to look into this for you.
