Diagnostics

RUN!!!!! I wish there was a rating much lower to give because 1 star will be more than generous. I took my car for a diagnostic, for 4-5 days we inquired about the results..no call. Later after numerous calls later we were told their mechanic had a mishap..still waiting..didn't hear back anything until the 5th and 6th day..I WAS then charged almost $200 for a diagnostics with a simple receipt, NO SUMMARY OF CHARGES OR RESULTS OF THE DIAGNOSTICS..Which I was told I could pick up on the 12th day of dealing with them. But yet when I question their business practices, I'm accused of being confrontational and poor ! Oh! and racist!.. Just because I expected an reasonable answer for such charges with minimum communication or detailed explanation of their findings. I took my Mercedes to Southern Imports in Kennesaw, dealer level expertise,professional treatment.. without the dealer prices.
