Club Factory — regarding refund of speaker of which was not delivered to me but shows delivered

Address:

1304, tower 8, bestech park view residency, palam vihar, gurgaon, haryana, 122022

SO[protected] is my order number. There were two items in it. I received a packet which stated that it had two items in it but only received one. I took a photo of the packet with the delivery guy at that instance only. I have called and complained to the customer care support of club factory and ecom( delivery partner) but they are not helpful. I need my money back somehow. I have the one item with me which is supposed to be picked by someone but no one is coming to pick the order. So I want to file a case against club factory for bad service, harrassing people and wasting their time and money. Plus, I want my money back. PfA the photo of the packet with the delivery guy.
