I was trusting you would have completed the entire fault code corrections , I wouldn't have paid you $700 to which I could have applied to paying the Mercedes dealer to fully correct the issues. I have called Mercedes Bens corporate in Morristown NJ and there are no open campaigns for my vehicle.. You were rude last time we spoke and said you didn't have time for me to simply write down what I needed to look into, because I'm not car savvy..I didn't argue ever with you, it a shame I feel so ripped off.. But now that I made it public you reply politely...
