Tata Motors — Issues with starter motor

We bought our truck from Tata motors about 6 months ago. The starter motors has been defaulted and not working. I made a complaint[protected] on Saturday 09/04/2023. The employee came and took the starter motors and told us that they will fix it. We haven’t heard anything since then. My truck is loaded and the party is asking for the delivery. This is not done yet. It’s been 6 days and they are just making excuses.
I’m going through loss and mental stress as well.
No one deserve this. This is not done.
Whenever I call them they always say we haven’t received your starter motor.
Is it really that hard?
What about the loss I’m going through.
What about my mental health.
I hope someone will get in touch with me
