missing tablet

<p>I purchased a tablet for them. It started heating and not turning on. But they insisted nothing was wrong and sent it back. I told them that I don't want the same tablet back and I am not happy. They said they will log another return and evaluate the tablet again. Now they don't even know Where the tablet is. And there is no rush in solving this from their side. And that asking me if i remember the courier that fetched it. It's been over a month now and I'm still waiting. </p>
