I ordered a set which includes Kurta and plazzo..when I rcvd the order I found that plazzo was missing..when I notified myntra they asked me to return the item..which is fine..when the exchanged item was delivered again the plazzo was missing..again when I notified myntra about this..they said they will ship the missing item...after this was communicated to me..I kept chasing asking date on which the missing item will be delivered..they kept saying they will update me shortly..mean while I used the Kurta as I thought I would not have to return it..n now myntra is asking me to return the Kurta..Isn't this called [censored]ing customers..I have asked myntra to reimburse plazzo amount..to which they have denied...
