Truecomretail — Product got cancelled 3 times after keeping me waiting 25 days

I had ordered an apple iphone 11 on 1st may with a GST invoice from flipkart and the seller name is TrueComRetail and the delivery date was on 7th may. But on 6th may  it was revised to 10th. On the 11th may got an email from flipkart that my order will be cancelled from the seller side due to some operational issues and I was told to cancel the order and place the same order again from the same seller and I did.
But the order delivery revised to 16 to 20th may again because of the same issue. On the 20th again I was told to cancel the order and place the fresh order and I did it again.
But now the seller TrueComRetail blocked me from placing the order because I have cancelled the order multiple times.
Seller and flipkart both kept me waiting for 25days and they blocked my Rs45000 for 20days without giving me my product. I am 100% sure that the seller is not giving my product because I have requested a GST bill for the same and both flipkart and seller are giving many excuses. Now Seller has blocked me to place a fresh order. So i can not place the order.
Please take strict action on the seller and seller as well.
