Getworth Cars---poor service--No confidence!

I have had nightmarish experience with Getworth so far.(Buying a Car).I saw a car I liked and contacted the company--they put me onto the salesman who said there was a lot of interest in this car and I would have to pay a refundable (if I don't buy )holding deposit ,which I did.He then told me they had not actually received the car yet (what was the photo on their websiteof?)I then got the runaround for 2 weeks from the salesman--not returning calls and answering only part of the e mails sent to him.2 weeks later test drive the car with 2 other witnesses and tell them that the electric mirrors are not working--can't adjust them--get told will be sorted out--"no problem".Eventually the car is ready--been in the panel shop (scary) and arrive at the the agreed time.Car is there but the number plates are not on and the person will be back later--after an hour and a half I sign for the car and off I go without the plates.On the way home I realise they have not attended to the mirrors,but not to worry I'm given a gentlemans name who sorts out any post delivery issues.I have since filled in the forms and sent them off by e mail to this person,who I now can't get hold of through the phone number on his card and when the switch board puts me through to his extension--it just rings and then cuts off and tells you to try again later.The whole journey I've been through buying this car has made me nervous and now that I can't get hold of the person and received no acknowledgement of the e mail as well fear the worst,but will update the situation as we go. Don't return calls--answer only selected queries,and can't get hold of anybody. How would the company rate this service?
