Paytm Mobile Solutions — delay in delivery and customer support harassing me

I habe ordered product on 24th december 2019 up till today, i was harrassed by support people as they were changing shipping and delivery dates, now my order has not been delivered. They even promised on a express delivery still no response form them. Till today i am stilk waiting for the order confirmation.

I had called each day for the update, still no response, i have paid the amount and still no order. This is second time the issue occurred, pay them and waste my time calling them.

They are not taking responsibility. My patience level is to the roof.

I was promised order wilk be delivered on 29th december 2019 due to delayed dispatch. But still false responses.

Please help, i am being cheated here.
