Worst customer service ever by Mercedes benz.

<p>My C200 went into Mercedes benz to have a new battery fitted and I paid my account i full.</p> <p>They didn't replace the battery.</p> <p>Over 7 weeks ago they promised to fit a new one.</p> <p>It is now 7 weeks since I paid them all my hard earned money for a new battery and I am still waiting for a new one.</p>
