Bad service

I booked my car in for a service around 2 weeks before the date. When I got there to drop the car off there was no record of the car on the system and I had to wait and give all the details again. No one even apologised. I asked them to see if there is a loose connection on the aerial as sometimes I have no signal in areas I usually have signal. I also complained about an echo on the bluetooth. When the receptionist phoned me she said all car kits have echos and the technician took a drive with the car and the radio worked. She said the car is ready I can come fetch it. I got there and they were still busy with the invoice and the car and once again no one apologised. Truly disappointed with the service! She also told me that the technician drove from The Glen all the way to Alberton and drove around in the are amd there is nothing wrong with the radio, yet there was a full 3km extra on the car....
