Bad customer service

This is the sequence of things happened today with me while i ordered food on swiggy i m more of a regular customer… Earlier this morning i order food for madurai Idly shop apparently the restaurant never got the order but swiggy was tracking that order to be delivered in 15 until i called the delivery exc i had no idea y was it taking so long and later in the day i ordered paneer rice bowl instead of that i was delivered chicken.. And then was also given replacement but unfortunately the delivery exc met with an accident nd the csr krishna promised for 175 rs coupon that never landed on my account and the escalation supervisor named hemanth was so annoying pathetic cust service skills and didn’t help me with any resolution and kept saying that dedicated team will look after m i suppose to be staying hungry for these mistakes that they do.. Its so annoying waiting for good from 9:30 till 11:30 and at last getting nothing… I don’t know but u need to make ur agents learn how to address customers concern
