"out the box" fortuner with 0km on has 15000km on the clock in the toyota APP

Dear TSA...

Sept 2019 i bough a gd6 fortuner out the box for CASH.

Was delivered with 100km on the clock... drives well, comfortable, ect... thanks a million guys...

20 months into ownership, i spoke to a pal witj a gd6 hilux and was told about the "rust above the windscreen" issue with the gd6 fortuners and hilux bakkies. He had a warantee repair where the rust was fixed and a clear film, similar to VSP was put on the length above the windscreen, gr8 work TSA...

now, back to my fortuner....

Im the 1st owner, haven't had this rust issue... but the film IS already above my windscreen?? Had a look at a unsold new fortuner on the showroom, no such film either... had a look at a VX down the road from me, no such film either.... why did MY "out the box" fortuner have this film?

Talked to this pal a bit more about this "strange" film i got "out the box" and he told me to check the odometer reading on my toyota APP.... My Fortuner has 16 500km on the dash odometer, but 31 000km on the toyota APP... 15000 more?

Please explain this to me, as i will be digging into this and if it comes to light i was sold a 15000km rust repaired "customer return", "dealer demo" pr some other issue where the clock was tampered with, ill be retuning this Fortuner and the courts can figure out the rest...

I'm waitint for TSA's explanation...

Im happy with the car, drives well.... but i didn't pay hard cash to buy someone elses problems.....
