Poor and unprofessional service. Review on Swiggy

Even after clear instruction to come with change as have no change or paytm available, the delivery executive shows up with no change and asks me to do paytm even though I clearly wrote that there is no paytm available. When I point that out, he gets rude and takes the order back and says will come back later. I keep waiting and then on the portal I see my order has been cancelled. When I inquire why, I am told that I now have to pay Rs.81 as cancellation fees. I never cancelled my order, infact was waiting for it as I was hungry and to my shock swiggy not only cancels that order on their own but even tries to extort money from me for cancellation, which I never did. This is not the first time, swiggy cancels orders without information and the delivery executives try not to give you exact change as they want forced delivery tip. This is not fair practice. If they do not have change they should simply not accept the order or advice before making you wait and then showing up with no change and being rude. I think this is not fair to make someone wait for food and then not deliver and worst -even try and charge them for not delivering.are you serious?
