Lenovo — No proper support after purchasing

Hi
I ordered my product on aug 2nd 2021
In order summary it shows delivery within 6 weeks
But it's been a month now
I called customer care and they said they expecting the product to reach India this week and I will get it by 16th September
I got reply mail from Lenovo stating that I will get my product only after 23rd September
And I got a reply from Lenovo team in twitter stating that I will not get my product before 30th September

Why can't they give a specific date ?

Everybody keeps giving different delivery dates

They aren't even bothered to keep their promise of delivering within 6 weeks

I paid 148000 to purchase their product

And this is how they treat me
