Myntra.com — ### attempt failed too many times

I have placed return Item on 19/06/2022, from that day i am getting messages saying our for pick up but, there is no person came to pick up or even called me, but I am getting message saying that pickup failed because of customer is not reachable . the same thing happened last 9 days.
today also got message and asked pick up agent will you come and collect he said he will come at 7 pm but still got same message saying pickup failed and customer is not reachable . how this will happened.
