Citroen don't want to refund my money!DISGUSTED!!!

I am so disgusted at the servuce we got at Citroen our car petrol pump that was replaced last year October gave in only in 3 months from fitted date it was replaced and we had to pay in 60% of the money ..The car is under warranty so the warranty company said they will only cover the 40%. Okay that was fine we paid .The car had another problem when the repair agent submit another claim that found out that the petrol pump that was replaced shouldn't have been paid for cause the part was still under guarantee a replacement claim should have been submitted and the part should have been replaced without us paying for it .when the repair centre Citroen east london for this information they communicated withe Citroen south africa and they said they not gonna honour the claim cause cake town Citroen where the first petrol pump was fitted didn't follow the correct procedure so Citroen cape town must refund . East london Citroen communicated with cape town where they requested all the paper work . That was in the beginning of March till this day d still waiting for Citroen cape town to contract us about our refund whenever I call they tell me that Citroen south africa keep on declining so my question is that till when are they gonna play hide and sick .I'm the only one that got a loss from this . We were ****** of our hard earned money . Someone gotta make the right decision and refunds us out money we have nothing to do with office politics. I'm really disgustedabout the service we getting ....**************** .
