We are sorry for any confusion , we always explain charges before the check. We did an intitial check and the brakes looked fine, at that time we explained further checks which include charges would need to be done to determine the exact problem. We will install the neded sensors with no labor charges to make up for the miscommunication. We always try to make sure everyone understands everything before charges are incured. There was no mention of misinformation or disappointment at the time the work was done or pick up, had there been we would have cleared this up for you at that time. Please let us make up for your disappointmnet.
