I sent one extra month's payment to TFS on a car lease which had expired. The experience of trying to get a refund from this company has been a true nightmare. The customer service reps are complete drones. Nobody answers their phone. Trying to get the name of a supervisor is impossible. I supplied them bank statements and they claim that's not sufficient proof.
Bottom line: I still haven't received my refund. In the future I'm avoiding TFS like the plague.
