3.5.4 If notice of a dispute with respect to a charge is not received, in writing, within 30 days after an invoice is rendered, such invoice shall be deemed to be correct and binding upon the Customer. In instances of a dispute, the Customer is required to pay the undisputed portion of the bill in its entirety. Accounts not paid within 30 days from the due date stated on the bill will be considered delinquent. Delinquent payments may result in the imposition of a late fee which shall be imposed at the rate of 1.5% of the unpaid balance per month or the maximum allowable rate under applicable state law.

3.5.5 If a Customer accumulates more than $1,000 of undisputed delinquent charges, the Company's Resp. Org. reserves the right not to honor that Customer's request for a Resp. Org. change and the Company reserves the right not to honor that Customer's request for a carrier change until such undisputed charges are paid in full.

3.5.6 The Company may require applicants or Customers to provide information pertaining to their financial ability to pay for service.
 

3.5.6.2 In the case of a cash deposit, interest will be paid for the period during which the deposit is held by the Company. After an initial thirty (30) days, the deposit will accrue interest at the rate not to exceed eight (8) percent per annum. If the Company, in its sole discretion, determines that the Customer is not capable of satisfying its payment obligations, services may be canceled by the Company upon written notice.

3.5.6.3 At the Company's option, such deposit may be refunded or credited to the Customer at, or any time prior to, termination of service. The Customer may elect to apply the deposit to future invoices or receive a payment of the deposit amount. However, if any balance is outstanding on the Customer's account at the time of cancellation, the Company reserves the right to apply the Customer's deposit and accumulated interest against the Customer's unpaid balance.
