No feedback from groupon

I bought a tablet from Groupon a few weeks ago. The courier company they used left my tablet with my neighbours child who is barely in her teens. She lost it as I never saw the tablet. <br> <br> I took up the matter with the courier company as they never bothered to call me about the delivery or ask my permission to leave it anywhere else. They were NOT helpful at all<br> <br> I decided to call Groupon cause I paid them for the tablet, I was hoping they will intervene as they are the customer of the courier company. I have sent emails to Groupon with no feedback, even called the call centre and they promised to escalate the matter to the logistics manager who will then take up the matter with the courier company used. The emails were sent 2 weeks back and again last week. The call was made last week Friday.<br> <br> Still today no feedback whatsoever. I paid for tablet that was not delivered to me. <br> <br> I want Groupon to take up the matter with the courier company they paid to deliver my tablet to reimburse me for their negligence <br> <br>
