I ordered a pair of pants for my customer. But they received only one piece and that tooo very worst quality when i return the product the delivery boy asking please give 2 piece then only we will take that product. If we get only then how can we return two piece. I communicate meesho customer care nearly 20 times but no one will solve my problem. What should i do now? We are working for part time if you people are doing like this how?i am earning 500 rs for 10 orders because of this issue now i loss 500 that is equal to 10 orders. Please help in this problem. Customer care are saying that client is rejecting we cannot do anything but in app they were showing that we canselled the return request why meesho is blaming us. Please solve our problem.
