Xindi Audi's service is very poor. Last year, I bought a car in Xindi Audi, promised to send a time coupon, and said that it was entered into the system. Maintenance this year requires time coupons. The system couldn't query, so I found a sales manager. The service of the sales manager is terrible. The sales manager said there was no system, so I didn't. I asked the seller who bought the car to leave.
