Very bad service never respect customer. Review on Swiggy

I had very bad experience with swiggy. Yesterday I was trying to order food of RS.870 in discount, payment was failed due to their error, 93 discount not applied on repayment with Rupay card, when called to customer care they refused to give offer and forces to pay full amount on cod. When I trying to cancel they are telling me fine of whole order amount and will be deducted from next order amount. On argument they agree to cancel my order without fine. Then I placed new order. I got my food 15 min late by promise time, also in my ordered food I got wrong food as well as uncooked, I sent them all evidence of uncooked and wrong food photos but for this complaint they give me only 20 RS. Coupon As compansation for my Rs.870 order. Total wastage of money. Me and my family are unhappy with swiggy. They are favouring to Food delivery partner not the customer. I will never recommended this app to anyone. Please delete this app from mobile and never trust such useless food delivery partner.
