Bergstrom Honda

My first shop visit was 09/24/11 because my civic's engine light was on.  I was told it was time for a major scheduled inspection so I had that done the same day.  I mentioned a rather loud rattling noise, when shifting from 2nd to 3rd gear (easier to hear if going up a hill) and a scraping noise when applying the brakes.  Front brakes were replaced, major tuneup was done, and was told the oxygen sensor needed to be replaced.  I choose to wait on the sensor since the visit was already costing me $600.00.  It was never explained to me that not having the oxygen sensor replaced might affect  performance, (I am clueless when it comes to cars) so I just thought it was emissions testing related, and since there is no emissions testing here, I wasn't too concerned.  Car running horribly and still hearing noises so brought car back in the next day and was told I probably needed an Idler Pulley to stop the rattling noise, and the O2 sensor is probably affecting power and performance.  Ordered the 2 parts, brought it back the next day. So 3 days of bringing my car in, and $1000 later, it's running a little better; not wanting to stall as much, but it's still running rough, the obvious rattle is still there, and the scraping noise from the brakes is still there.   An hour ago the muffler broke off from the main exhaust pipe,so I need that repaired.  I hesitantly decided to call Honda and mention I'm STILL having problems and now need the muffler replaced.  The receptionist, "L",  answered the phone.  I asked for Honda service.  She asked if I needed an appointment. I told her I had a service complaint.  As she responded, my dog barked and I didn't hear what she said, so I said, "I'm sorry?"  So she repeated herself very condescendingly - "Would  ----  you --- like ----to ---speak --- to -- a --- manager?"  I said, "Yes, please".  She put me on hold. I decided to hang up and write a review instead.
