Replace Lexus Gearbox

We sen our Nissan Patrol with an Lexus conversion to Lexus V8 Conversions in Pretoria North because there was an problem. Jannie and his mechanic opinion was this job is done wrong.<br> He give us a quote to service the gearbox, replace the visco fan and oil cooler.<br> After 5 weeks the car was not fix, he tell us we need to replace the gearbox. R18 000 will be the total cost.<br> We didn't have an choice so we say he must go-ahead. <br> Gearbox replaced and since then the car goes back every week.<br> I send him an sms to say the gear box make noises and it's not fix. There is still an problem, we are going on <br> leave to Jozini and Kosi Bay if the anything happen with the gearbox he must collect the car and give us an car the use until our leave ends. The car must also be able to pull our boat. We have a breakdown on the gearbox as I am taping this complain. We phone Jannie to say we stuck on the road. He say he is not an towing company, we must make a plan to get the car to him in Pretoria North. He never reply to my sms and when my husband phone Jannie regarding the gearbox that break down Jannie put the phone down in my husbands ear.<br> He give us an 1 year guarantee on his work and gearbox.
