Faulty device

I've ordered something a few months ago that is under warranty but Onedayonly. I've logged two tickets with no reply, sent an email also no reply than I had to chat the stupid bot on WhatsApp than another bot which seemed to be a person asking me questions that were on the logged tickets and also the email but they asked me to repeat it cause their IT division which don't know what to do. All around the this experience and onedayonly are pathetic.
