Waiting for reimbur*****t since November 2015 - unacceptable

Since November 2015 we wait to be reimburse for out of pocket expenses incurred after our Mercedes Benz GLA 220 CDI has a breakdown near Colesberg . The car was still under warranty and after we have submitted our claim to Mercedes Benz SA still has not reimburse us with the expenses incurred.

It is been seven months later and we are still not be reimburse.
