Bad service and faulty products!

I recently bought 10 powerbanks from Groupon, firstly they took longer than 14 working days to arrive, and then once I recieved them I noticed that they were also faulty. I tried calling groupon and was told that I need to send an email, which I did, however the response was that I needed to log the complaint online, I have tried doing this numerous times but with no luck, since then I have been trying to call groupon and the phone lines are busy, I send emails and unfortunately no body responds to the queries and questions within my email.<br> <br> I am extremely frustrated by the bad service, and would appreciate someone to contact me telephonically regarding this.<br> <br> My second complaint is that I bought a fruit juice blender / smoothie maker on the 27 Nov 2015 and was promised the product would be delivered in 10 working days, it is now 25 working days and still no sign of my delivery.<br> <br> Really really frustrating and with service like this I'm not sure that I would want to use groupon again!<br> <br>
