in app , this doesn't work . it's redirecting to payu only in desktop site , it seems !!so you enter dc at mkwik first,
cancel at otp if Payu
again enter dc but at payu this time and cancel again at otp
at this point in payu enter cc details
thats it
so you cancel twice and final enter cc at 3rd stage
I only did this in laptop and hence not sure if this works on phone
