I sent my daughter in for a long needed oil change. She had a coupon for 16.99. They told her it would be $70 for all synthetic (elwhich was a lie). I approved and paid for it. After leaving, an hour or so later, her car would not start. She took it to autozone for diagnosis and was told it was a sensor in the oil system. I had her call Calvert’s to take it back in. The manager screamed and cussed at her as no man should talk to a woman, much less a 19 year old girl. I then called and asked for the manager. I was put on hold and then disconnected. Thinking it was an accident, I called back and was told to never call there again. Keep in mind, I had only asked to speak to the manager. I then had her take the car to Firestone. Calvert’s had never even done an oil change. The car was 4 quarts low. They saw a 19 year old girl and believed they could take advantage and did. I paid $165 to Firestone for diagnosis, plugging the sensor back in and an oil change. I called Calvert’s corporate office. Initially they seemed concerned but then didn’t return calls or emails. All I wanted was my money back. This was a very very expensive oil change. The employees at this location are abusive, lazy, dishonest and unethical .
