Now below issues are i am having

1) my auxiliary input problem was not resolved, which i told more than ten times to the executive.
A) my new auxiliary cable is not present in my car, which i kept for testing

I want my auxiliary input cable and the problem to be fixed.

2) i provided a new key cover to change the existing key cover.
Key cover is lost/misplaced by the executive, now he is saying the below two points.
A) it is there in car and he forgot the change (I am not able to find)
B) i gave it to his colleague and not him.

I want my key cover to be replaced.
