Meesho — Blocked account WITHOUT INTIMATION

Hi, yesterday I got the delivery of the product with order no[protected], I had placed order for black jeans size-32 and received wrong size and the design is also different from the product shown in the APP, Now I am unable to place return request also, as they black marked my account, without any intimation or anything specified from their end regarding this block, i arrange a callback from their helpcentre, in between they're disconnected the call without i want to return the same and I HAD PLACED ONE MORE ORDER NO.[protected] WITH THEM WHICH I DONT WANT NOW, I AM UNABLE TO CANCEL THAT TOO, KINDLY HELP ME OUT FOR THE SAME.
