OT HAPPY ABOUT THE SILENT TREATMENT ON MY COMPLAIN AGAINST AVIS

I contacted MIOSA last year 2025 March about the VW polo that I bought from Avis. They never gave feedback and they didnt manage to resolve my query. And everytime when i send an email they just read and do not respond. I am worried that the supplier should have bribed them to remain silent. It is now 1 year and 3 months now with no feedback at all.
