Poor service from Avis - Maintenance Plan

I have a 5 year/60 000km maintenance plan with Avis on my VW Polo Vivo. I bought the vehicle in February 2018. To date it has 17638km on the clock. With lock down in 2020 we were unable to book scheduled services for our vehicles. Even VW and other companies extended their warranties and maintenance plans for 3 months till end of June. Why was Avis not one of them?

I took my vehicle for a service last week, as the service indicator showed, and was informed by VW my maintenance plan with Avis has expired end of February 2023. Phoned a number of contact numbers on the Avis website and their customer service and no answer. Emailed customer service and no reply. Poor customer service to say the least.

I would like someone from Avis motor vehicle maintenance plans to contact me as I cannot reach them by phone or email.

Thank you
