Abysmal service from Avis Car Rental

Worst car lease company in the country . Terminated my lease, and arranged to collect vehicle 6 days ago. I waited all weekend, sending numerous emails, complaints and two telephone conversations. Still no collection and the audacity to send me sms message at 10pm at night to tell me the vehicle is overdue and I should treat as urgent. What pathetic and abysmal levels of service . Various complaints to the customer service email also did not receive the courtesy of a reply . Would not recommend them at all. What a dismal experience after loyal support for years . Zero rating and not a pleasant experience at all!! Contract number RA ***
