After having my engine die (covered under warranty), my vehicle was taken to Mazda of Clear Lake on May 22nd. After being told my vehicle would be ready on the 10th or 11th, they kept pushing the date back. The 13th or 14th. On the 17th. Finally, on the 19th, they told me they 'by chance' found a problem with a cooling fan. Not having a satisfactory answer as to why this was important, or if it was covered under my warranty, I decided to call Mazda to express my concerns about the length of time it was taking, as well as the strangeness of the man handeling my case. They said it wasn't covered, but it's strange this is taking so long and they would call Mazda of Clear Lake for me. I also decided to have my boyfriend call to get more information about the car (I don't claim to understand cars at all). He called, left a message, and received a call back from the man handeling my car- who BERATED him for my 'badmouthing' him to Mazda.
Now, if he had a PROBLEM with what I said, he should have spoken to ME rather than my boyfriend. He should have had more professionalism- even if I HAD said something wretched about him- which I didn't. However, my nightmare doesn't end there.
I spoke to the service manager and he 'counseled' the young man in question, and took some money off the service charge. Fine.
Then he calls me a few days later and said they broke my radiator. Don't worry, I was told, we broke it, so it will be of no cost to you.
Imagine my surprise this morning when I FINALLY went to pick up my car (The 26th of JUNE), to find that I was charged for the fan AND the radiator. Not labor, but the parts. I didn't say anything to the service manager at that point, just wanting to LEAVE this place!!

Now the GM isn't taking my calls or responding to messages.

PLEASE don't take your car here for service! I'm sure their sales associates are very kind and trustworthy, but the service department- NOT AT ALL! Save yourself TIME and a HEADACHE and take your car ANYWHERE else for service!

***********************UPDATE******************
The GM NEVER called me, and now my engine is MISFIRING AGAIN. I feel I have been dealt the equivalent of having the chef spit in your food when it's been sent back for something.

So: You want horrible service where they don't do things correctly and treat you like an idiot??? Here's a good place for you to start.
