Avis is horrible and disgusting

I rented a car from Avis. I returned the car and waited for my deposit refund. Nothing was happening so I called Avis customer support and after over ten cal and hundreds of excuses, they said my refund has been processed and will reflect in my bank account afert days. Five days later no refund in my account. I called and they put me on hold and after few minutes they hang up. Some companies must just shutdown.
