This is the actual message received yesterday...if it in this case the courier person need to call...
If he called I should find the track of Flipkart miss calls...I didn't find in my phone...
The message should be as the courier person unable to contact me...but the message is unlocatable.
So I have again linked to the site and made again the delivery date update.
Today I have received the message as the courier is coming...
Now I received the call but I'm unable to pickup at the moment so I called back
.but it took so much time to connect to the concern
After so many attempts the person responded but with a rude nature wjich is not at all acceptable behaviour he replied as it's not going to delivery anymore...as already attempts made.
I[censored]r service is not going to do the required then what is the need of You to connect with Meesho and I need the product by to day...
So I need to see how it going to deliver my product.
The person asked us to do complaint ...what I want to do he asked me to do...is with this type of behaviour Ur hiring the employee
