I am writing to express my extreme dissatisfaction with the service my son received today regarding a flat tire on his rental car. He is currently using a rental due to a recent accident where his own vehicle was hit by another driver. When the flat tire occurred, he contacted your company for assistance. He was informed that he could either pay out-of-pocket for the tire to be fixed or replaced and then be reimbursed, or the car would need to be towed and he would be picked up to receive a replacement vehicle. As a college student, paying for a new tire upfront is not a viable option for him, so he agreed to the towing and replacement process. Unfortunately, during this call, my son encountered a specialist named Carolyn who was exceptionally rude and argumentative. To our disbelief, she even hung up on him. This level of customer service is completely unacceptable and the overall experience has been far below any reasonable expectation.
