bad service and dont want to pay

not the best mechanical warranty to join, i really regret joining them, it has been two weeks and no payment to the mechanics that were fixing my car , they calling me everyday asking for their money from impac but impac has not paid for 2 weeks , busy saying the invoice is incorrect, while there is nothing wrong with the invoice.... such bad service should not be tolerated @Roshe Mills, please pay MFC panel beaters for fixing my car and stop finding ways of not to pay. ref: CNECVAZ00105
