Pathetic Service Delivery!

Pathetic! I took my Citroen C3 in to have the fuel injectors replaced. It had to be imported of course due to the lack of parts in South Africa. I pre-paid almost 27K in cash and was promised a 2 - 3 week service delivery. Time past and is now over a month and when I followed up where my parts are, nobody could give me a answer. It came to light that the Warehouse of Citroen was relocated and everything has been a mess. I was informed by Citroen Head Office that a investigation will be launched to find out if my parts was in fact shipped to South Africa and they can only apologize for this. Apologize??? How do you apologize for a R27000.00 mistake or error??? They were quick to ask payment but now when the pressure is on they can't give answers - so yes, I am sitting with no car for aover a month with the car being at a workshop with a open engen gathering dust - which obviously I will claim from Citroen for damages should it occur!!
