finance was settled but still deducting debit orders

First of all: why is no one answering your phones? I have phoned so many times, and there's no answer, how am I suppose to contact you? No one has the time to sit on the phone the whole day waiting for you.

Second of all, since I can't get hold of you, I will complain here. My car finance was settled in full with you, yet you still processed a debit order from my account. I would like my money back please.

HOW CAN I CONTACT YOU?

Sincerely, A very frustrated client
