Hose leaked after a few uses

I ordered this hose in July, and we only used it a few times (less than 10), now it leaks. I would like to get a replacement hose. In a review from Nov 2018, I saw the seller answering to contact him via email to get a replacement hose and emailed him but never received a response to my email inquiry. PLEASE TELL ME WHAT TO DO TO GET A REPLACEMENT
