Never do business with Prowest

We traded in our Vehicle on the 18th September, when we collected the car there were problems, we were told to take the car for the weekend and come back with anything else that is wrong. The mirror was broken which we fix ourselves and the airbag light is on. A month later we are sill fighting for them to fix the airbag as advised by them and documented on paper. Zakel does not answer our calls, he is extremely rude, arrogant on the phone. Martin the manager has done nothing either I have sent through all that was asked and still nothing, no reply to e-mails either. What kind of service is this? It is now the 20th October and still nothing, if my boyfriend get into an accident and there are no airbags and something happens to him, insurance wont pay out ether. <br> Save yourself the hassle. I have also been begging them for the road safety certificate and all I got was a print screen on something. Is this legal. I am now going to be seeking legal advise.
