We apologize that your experience did not live up to the previous experiences you have had at Feehan's. Obviously we strive to make our customers happy in any way that we can. We always try to be fair when it comes to diagnostic charges and only charge for them when we feel we have spent enough time looking at a vehicle to justify it. Our policy is to always make our customers aware of any charges that they will have before performing the work. In this case, obviously that did not take place and for that we are very sorry. We would like to offer you a free oil change in order to make up for this. We certainly do not want to lose you as a customer. Please give us a call to schedule your free oil change whenever your next one is due.
