Ecom Express — Return not picked up twice

I am writing to you may be 5th or 6th time for pickup of my order. My earlier AWB no was [protected] which did not get picked up rather without coming to my place the pickup executive will send pickup cancellation code (even when I have not requested cancellation). This happened again for the second time in a row, my reverse pickup got re-arranged and this time my AWB no is [protected], again no body came to pick my order today rather I received a pickup cancellation code. I am totally frustrated, Is this the kind of employee/ Delivery executives that you hire who are not ready to work just keep sending cancellation codes. Request to esclate this matter
