[Resolved]  Swiggy — Cancellation of order automatically

I ordered from swiggy and it take 1 hour instead of half hour and then they just cancelled my order.. I immediately contacted them and they told me that delivery boy cancelled it because it couldn't contact me.. what kind of a excuse is that the delivery address was given and it was not hard to find.. my location was on too
This only happened because I paid for order online? And they can have the cancellation charges very easily
Customer care didn't did any help and won't listen to my suggestions.. this is so wrong
