13. Customer A raised a dispute with the debt collection agency, which halted collection
and made enquires with Avis. At this point Avis reviewed the charge, determined

cease collection. Customer A was informed of this outcome by Avis on 4 April 2022.
14. Customer A was told by Avis on 13 April 2022 that the charge was a portion of the
excess he was liable to pay for damage to the vehicle incurred during his rental
period.
