Royal Enfield — royal enfield interceptor 650 baker express

I had booked royal enfield interceptor 650 baker express on may 5th 2019 at teknik motors and they had promised me to deliver with in 45 days.. Now it’s been close to 90 days but i am getting false commitments on daily basis even after several follow ups from the store after full payment.
Now they are saying we will credit back your amount.
I request you to treat this with high importance and do the needful immediately.
