Broken promises, Avis fails to follow up

Absolutely appalling experience with Avis Car Rental! After returning my rental van on time, I've been waiting for what feels like an eternity for my deposit to be refunded. Despite numerous calls to their call center, the issue persisted. It wasn't until I escalated the matter through a new complaint that the team leader John Dube was supposed to follow up. However, even after this escalation, the team leader refused to call me back to address the issue, even Carol at the refund department did not have the decency to call me back or even take my call, hanging up on me at one stage when her colleague tried to connect my call, the lack of customer service and follow-through is shocking. Avis, you need to seriously revamp your refund process, customer communication and customer service, as this is a big contradiction to you voice over on a call or disclaimer "at avis people will always be more importantthan cars". Until then, I'd advise others to think twice before renting with you."
