I have received a response from their country manager and he has committed to replace the batteries by today, I have send him a reply that if its not done today, I am going to buy the batteries on my on and will file a case for refund of my money for batteries.

I don't think they will be able to do it today also....

Tomorrow I am buying Amaron shield batteries 100AH ...got a deal of 6.5k for each.
and then I will file a complaint in consumer court.
