Toyota Vitz 2014 CVT Transmission Oil Change Story

I recently purchased Toyota Vitz 2014 from Jan Japan showroom situated at Super Highway. Toyota Vitz in Japan is called Yaris and its is different from Toyota Vitz. I went to a mechanic shop in Phase 2, DHA, Karachi and told mechanic for test drive. After test driving my car the mechanic told me that my 1KR Engine Crankshaft is making noise while acceleration. He told me that he can repair in Rs.25,000/- I was very much disappointed and went to another big workshop in DHA, after test drive the mechanic there did not mention about crankshaft noise but told me that I must change Automatic Transmission oil and he will also clean Automatic Transmission filter. Further he told me that your car is not taking pickup therefore he will also clean exhaust Catalytic Converter. Mechanic told me that labor charges will be Rs.3500/- and CVT oil of Toyota will be Rs.5500/- I was not still satisfied with this mechanic too. Then I decided to go to Toyota Defense Motors Karachi.
I have bought Toyota Vitz 2014 model recently for Jan Japan showroom which is located at Super Highway. In Japan Toyota Vitz is called Yaris and Its specs are totally different from Toyota Vitz. I went to Phase II DHA Karachi and visited a mechanic shop and told mechanic for test drive. The mechanic told me that the car 1KR engine Crankshaft is producing noise after test driving. He said that he can repair and will charge 25, 000 RS for this
Toyota Defense Motors checked the car as a whole and it was working properly. Everything was fixed. The mechanic test was conducted by Toyota on Korangi road and it qualified it. On the high speed car stopped and producing a noise when brake paddle pushed. It seem that something is breaking in the wheels. When I asked about this noise by mechanic, he told me that the breaks are built with Anti-Lock breaking system ABS. The car in the high speed can hit without ABS. In low speed the noise from brakes will be vanished.
After complete checkup of my car, the Toyota Defense Motors told me I should change the fan belt and wheel bearings only. the mechanic told me that you need not to change automatic transmission oil unless it leaks. Toyota has not provided any Gauge for measuring CVT oil because it is not changed even after 80,000 mileages. Change when it leaks o r after 150,000 mile check it by Toyota Workshop only. They also said if I allow they will change the CVT oil as the engine light might give a blink error. They said, you should change it after 150,000 miles and check it by Toyota workshop only.
When I asked Toyota Motors price of Vitz 2014 fan belt they told me it will cost me Rs.95,00/- and one wheel bearing price is Rs.5,500/- Now I decided to go to Plaza for fan belt and wheel bearings and when I will find these items then I will fix them by any good mechanic of latest Automatic Cars. I am also in search of Toyota Vitz 2014 pdf manual but could not find.
I asked about the Toyota fab belt price, they said that it will cost Rs 9,500. And the price of wheel bearing is 5,500 Rs. I will now purchase from market and get it fixed in the car by approved Toyota Workshop from a good mechanic. I also need Toyota Vitz 2014 manual but not found. Finally I will suggest you all not to go any street mechanic for the wastage of your money and time.
