BROKEN ENGINE MOUNTING

Good Morning, i filed a complaint on the 4 February 2015 on Hello Peter and received a response. I did not take the matter further because Tony from Bosch Toti contacted my husband immediately to repair the part. He gave us the run around saying his waiting for the part from February till May. He eventually fixed the car and used my warranty for the repairs confirming that he has now fitted original parts and not inferior parts as previously done. It is not even 3 months later and the exact same part is now broken again. I have taken the vehicle to a reputable mechanic and he confirmed that the part fitted is not an original VW part. Please assist as I am tired of dealing with *********** people,I have this vehicle going on 2 years this month and its the fifth time this exact same part has broken. I do not have any records as Bosch have been dealing directly with Durban South Toyota,where I purchased the vehicle and they have given us no paper work even when we asked them for receipts and invoices.
