Utterly useless service at Sandown Mercedes Benz

So today I tried in vain to make a service booking on the useless Mercedes booking website! What an utterly useless system and a total waste of customers time. I then tried to call them at least 5 times with the phone just ringing off the hook. I finally got hold of someone on the telephone, expressed my amazement that someone actually answered the phone, told them I was totally frustrated and was on the cusp of making a booking through a private service operator instead and asked if I could make a booking. To my utter amazement the lady on the phone said that the booking lady was busy with a customer. Not can I get someone to call you back. Not can I take you details. Not sorry about the inconvenience. I then said that I was sorry to have troubled them and indicated that I would book my car somewhere else! The reply from Mercedes was ok no problem!!!!!!!!!
