I ordered icecream through swiggy app n paid for it but during delevery of the ice cream they showed some different address to the delivery boy so he was not able to deliver the ice cream n he cancelled the order n when I called the customer service they said that it was my fault that i didn't receive the product..i told them that u showed different address to delevery boye how can I get the order i have clearly mentioned my address which is of my bank n it's located on the main road of the city...they denied by saying that they can't do anything on this matter...why should I pay for there technical glitches when I have clearly mentioned the address n they show some other address to delevery boy
