I am a regular user of swiggy.but their customer care service is horrible.
First of all they will never understand your problem.and you will get one reply in 5 minutes.their response is very very slow.and if you delay in replying they will close the chat window without resoving your problem.
last night it took 90 minutes before they culd understand my problem and resolve it.most of the contact details mentioned on swiggy are wrong.if yu try to contact the restaurant you will never get an answer
