Repairs not done right that was payed for

To Who it may concern.<br> I have a NP200 that I bought new at Nissan Midrand and have full service history by them with no complaints. Was driving to Krugersdorp Friday after work and the fan belt climbed off and hurt the engine. My insurance said they only will tow the bakkie to the closest Nissan that was IC Auto Nissan Roodepoort. It was raining and got to them just before 17:00 every body was packing up why. To repair the damage the head must be done and 2 valves must be replaced and other stuff so I said fix it the total was R 16,845.29 that I payed and was told there is a 1year warranty on the work. I noticed the bakkie didn't have must power and it was dripping were it never did. Gone to Nissan Midrand I told them the whole story because they know me very well a customer for 4year pus. At the back of the motor the oil is leaking from the head. Bakkie at Nissan Midrand and said they get no response from IC Nissan so they can fix my bakkie now 8days.This is a dealership that glues bolts to my engine because it the wrong bolts on the spark plug wires that why it didn't have power. Besides the fact goods ****** out my bakkie still no answer on that also.
