Very Poor Service

We had an accident Early December, vehicle was sent to a panel shop in Queenstown, i was called by the agent dealing with the claim, he advised me that the vehicle was a write off, He requested settlements and other information from the bank, i sent the same to him, i traveled to Durban and started looking for another vehicle and line up a few options, he called me later in the day advising that this was a mistake by the assessor ,mistake with the vin number, he is waiting on feedback from the assessor. i thought this to be a human error and asked them to sort it out asap. after a few follow ups, he called me on 05/01/2015, he apologized for his mistake and he advised me that the vehicle was indeed a write off and requested new information from the bank, i arranged this from the bank and sent the same to him again, he then called me back advising that everything is gone through, the bank will be settled immediately and the balance will be paid out to me. He called me at around 16H30 advising that this was a mistake again with the vin number and that and will be rectified as again he got the wrong information. not sure what's going on and My courtesy vehicle expires shortly.
