No good customer service and attitude. not happy and satisfied. Will never recommended to my friends. Regardless of the cost, they install extra in the car without asking me.. Their response is this is not a big issue, no need to make the phone call for small amount of money. They can not make each phone call to inform customers what they did And how much will cost.Too much excuses for not doing things in the right way. At last, they did not even find the problem.
