National Tire & Battery [NTB] review: dishonest company - unethical company and personnel

Company tried to scare me into purchases which were unnecessary and would not honor my alignment agreement. I took my vehicle in for an alignment already paid for in my alignment agreement. I was told they would not perform an alignment unless I spent approximately $700 in (unnecessary - I have proof) replacement of my wheel bearings. I did not have the service performed but took my car to my certified and Mercedes trained mechanic for his opinion. He said my wheel bearings did not need replacing. I then researched normal life of wheel bearings for my car and, per Mercedes, the normal useful life is between 100, 000 and 150, 000 miles. My vehicle had 66, 000 miles and is at least annually taken for complete service to my Mercedes trained mechanic. I also asked for a nail to be removed from a tire (I also had paid for complete tire protection from this company). They said the tire was damaged beyond repair and I would need to purchase a new tire. The tire had approximately 20, 955 miles. They removed the nail but said the tire would be flat as soon as they took it off of the rack. I have driven on this tire for over 2.5 months and never had to add any air. Apparently, another major scam by the company against a senior citizen. I have the documentation from this company to support their required charges.
I want this instance of dishonesty to be documented in their record for others, especially senior citizens, to see when they research this company.
