Terrible service and poor communication

It has been 3 weeks since I last took my car for service and have no idea what job was done on my car. The receptionist said she'd send me my statement on the day of pick up and there's still nothing. I called in last week and she said she would send it. What kind of service you are running there, I dont know. I am driving around with a car that's making funny sounds every now and then. It is a little stiffer to drive since the service. And the service department couldn't be bothered to send me my statement. I have been patient for 3 weeks and now I am not a happy customer! This simply shows how little they regard customers!
