Boat — Refund no received even after 45 days

I ordered a boat with order id 417996 watch on 30th May 2021, its been 45 days since I still haven't received the product .I called customer care several times and they said the order has been cancelled by the courier service and we are refunding the amount.
I called several times for the refund every time they say i will receive the amount in 3 working days but still i didn't receive the amount yet.
When ever i call, new customer support executive lifts the call and says the same thing.there is no proper response from them
Please help me in getting either the product or Refund
