Bigbasket.com — cashback communication unclear, big basket does not want to resolve

The code used to get a paytm cashback was not clear on where the code had to be inputted in order to get the cashback. It just said use at checkout but whether to be used on the big basket app or on the paytm app was not clear. Finally i spent the money with big basket unable to use the code. When i called customer service to complain about this, they said they were very sorry but could not resolve this. As a merchant who is offering the cashback and when all criteria's were met, i think a merchant should have means of resolving such issues.
