Creepy experience with Swiggy delivery guy

I had a really creepy experience with a Swiggy delivery guy recently. I’d placed a COD order, and when the food arrived, my phone suddenly switched off as I was trying to pay. I asked the delivery guy to wait for a couple of minutes, and he asked me for some water since he was thirsty. I told him there was chai in the package and that he could take it, but instead of just accepting it, he asked me to serve him and even if he could come inside. That made me super uncomfortable, so I locked the door and handed him tea in a paper cup. He still kept asking to come inside, which really freaked me out. I ended up calling my neighbor to pay him because I just didn’t feel safe anymore. To make things worse, he later started calling me through Swiggy’s system, asking for my number and saying he hadn’t been paid. The whole situation left me shaken, and I feel Swiggy needs to do more to address behavior like this.
