Bad service

I hired driver and registered the car under Uber, the driver was working for someone under his Fleet then when he stopped working for him in December he sent a email to Uber requesting to be removed from the fleet account. He was advised that he must ask the owner of the fleet account. He did and owner confirmed that he removed him. It's been four weeks and we haven't received payment. Unfortunately the fleet owners account is blocked due documents being expired and we not sure if Uber is paying the money into his account. We set an appointment with Uber to discuss this matter they agreed to call us but till today we haven't received a call.
