Avis tries harder ? I think not.

<p>Following an issue that I have had o several occasions with a car supp**** "full" from my local Avis branch when it self evidentally was not (petrol slips provided to prove this at the return) I have tried unsuccessfully to get a satisfactory response from the company. Whilst credits were made for the difference each time, I still require an answer as to how this kind of deceit can be allowed to happen from Customer Services. Every day for the past ten working I have tried to call them on their ********** 111 number and EVERY time am told that due to high call volumes I should call back or send an email. I have sent an email twice to an individual there and to the service centre itself and received no reply whatsoever over the past three weeks. Avis tries harder ? You decide. </p>
