I don't know what is going on here. I have been a customer of this Store for over a decade. I needed new tires and scheduled the installation on line. I indicated that I would wait. When I arrived at the appropriate time, I was told that the service people were going home. They would keep my car overnight and do the install first thing in the morning. I asked what time would it be done, I was told by 9:30AM. Thursday June 30 I called at 0945 to see if the car was finished, it wasn't. I ended up picking the car up at 11:20am. The next day, July 1, I received an email from NTB indicating they have a buy 2 get 2 free offer. I called and spoke with the sales person, she indicated that she had no control over what corporate did. I asked to speak to the manager and was put on hold. After a period of time the sales person picked up and indicated that the manager would honor the new offer, however my installation package would change. I accepted the change. Now I was put on hold again for an extended period of time as they tried to figure out what to do next. I think they expected me to say no thank you and hang up. Short story, I called and spoke with Kevin Beach the manager. He indicated that indeed they would honor the new deal and that "George" was working on the figures. George would call me back. 35 minutes later, it is now after 5:00 PM, I called and asked for Kevin. He was gone and George was with a customer. The sales person indicated that they would refund the original sale and re-write it with the new terms. This means the original sale amount would be held on my card and I would also be charged the new amount. That was not acceptable. The cost difference was $62.47 and the addition of two services on my computer record. They either could not figure out how to do that or they are not allowed to do that. Either way, I told them to forget the change. I was not having over $600.00 held on my card and another $700.00 charged to it. After over 10 years and multiple cars serviced here, I am through with them. There are many other options open to consumers.
