Review on 🖨️ V4INK 2-Pack Compatible 26A Toner Cartridge: Premium Black Ink for HP Pro M402/M426 Printers by Larry Boyd

I ordered these cartridges in January 2019. I have a cartridge or two on hand. So when I put in my last cartridge in January, I ordered these cartridges. I put in a new cartridge yesterday. About 15 pages were printed and nothing was printed on the following pages. The return message states that the return window closes in February, which is a month after my order date. That's not acceptable to me. Please advise how I can return these cartridges as they are not working. Many Thanks.
