Meesho — Did not received exchanged product neither refund

Address: BANGALORE, KARNATAKA, INDIA

I ordered a face pack brush in which 4 brushes should have come but only 3 brushes came, so I filed for an exchange, the product was picked up in 2 days, and till now neither exchanged product nor refund money has been given.
When I talked to the customer care of Meesho (and that too 7 times), they did not even pay attention and spoke very unprofessionally and 2 of them hung up the call without even listening to me properly. That is very rude and not trustworthy.
I WANT A FULL REFUND OF 124 RUPEES AS SOON AS POSSIBLE.
ORDER PLACED ON 20TH JULY 2022
DELIVERED ON 23RD JULY 2022
PICKED UP FOR EXCHANGE ON 25TH JULY 2022
NO RESOLUTION OF COMPLAINT TILL NOW.
