Very bad service from Avis

On 23 Jan 2025 I hired a car from Avis and dropped off on 1 Feb 2025. Everything was ok. A couple of days later I get an invoice for toll fees, but none of the roads I went on had tolls. Invoice number E*** I have emailed customer service twice requesting the receipts for the tolls or to credit my account, but Avis remains silent. This is really terrible service from Avis and not what I would expect. I will wait another day or so and then take my complaint to the consumer council.
