Citroen C4

I bought a 2011 Citroen C4 in 2013 from the Citroen dealership I East London and since the purchase have only placed 7000 km on the vehicle. The car has overheated twice and both times have been to CITROEN for repairs. Less than 6 months from the last overheating problem the vehicle has overheated again and this time has caused multiple damage to the engine. I informed Citroen regarding the overheating issue and they insisted that I drive it to them. I explained the severity of the overheating however they insisted I drive the car to them. They kept referring to a sensor issue. They now want to charge me R 22000 to repair the vehicle. They app**** to Citroen SA to cover the repair costs and they are prepared to cover R 5400.....clearly they don't give a he'll about me as a client. One thing is for sure is that I have a wide influential base of clientele and friends and will most certainly advise them to choose an alternative manufacturer. This was my first experience with Citroen and it will most certainly be my last. Truly dissapointed
