cultural creation2021 - old used product delievered

i ordered printed kurta pant & duppatta set size XL amount Rs. ***/- . Its a prepaid order so i got Rs. discount on this product and i have paid Rs. ***/- The product was delivered on ** July **** at *.** PM. when i reached home after my work i opened the packet and saw that it was two old used shirts. I put return/refund request on the same day i.e. **/*/**** at *.** PM. After some delay at my and their end i returned it back on **/*/**. they have not updated the status yet and asking for return slip which was not provided by their delivery/pickup man. this is not the first case. This happened with me *rd time. it is totally useless and rubbish app. I am an expert user of Meesho app I am not new here so that they are asking me to show return slip which was actually not given to me.
