Service was very bad.

I had a problem with a battrey. I took my car to battrey centre. They ask me to leave my car and re charger my battrey. The guy that was working there ask me to pick up my car at 17h30. When I reach there battrey centre was close with out a notice. I found my car parked and the window was open. One have call me that are closing early. No even try to call me. It's real unfair. Anything could have happen in my car. The battery is only six month old
