Avis not responding to request to release money held on account

Unfortunately, we are not receiving any support from Avis with regards to the release of funds held on our account. We understand that COVID-19 has had some serious operational impact on businesses, however, given the summary below we believe this is poor service even during the time of the pandemic.

Summary: (1) Funds reserved for vehicle hired on 4 Aug 20 (2) Vehicle returned 5 Aug 20 - no incidents, 1 traffic fine (cost paid) (3) 13 emails send (4) At least 20 phone calls

Currently not getting any response from the call centre or the emails sent
