Worst customer experience

I purchased a second hand car from the dealership around Fe b 2015 and i did not get the full service book for the car. i have been trying to sort this out with the Sales person Theo but it shows that VW sales people only care about making a sale and could not care less about the customer. till this day i have to follow the dealership around to beg them to sort this out...this is the worst services and i regret going to this dealership everyday!!<br> <br> if i now decide to sell this car the value will drop because of how careless the dealership is with important document.<br> <br> <br>
