GROUPON HAS THE WORST AFTER SALES IVE EXPERIENCED

Last year I bought a Acer Iconia tablet from groupon and have emailed them countless times to return it due to the sim card slot in the device no registering any sim cards meaning i was unable to use the device. I emailed them to return it but nobody responds and the call centre doesn't answer.<br> <br> This year I bought a driving lesson groupon and I used one but then another was given to me as a gift and I was unable to claim it from bluespark because they say that the same person cannot claim the same voucher and i must ask groupon for a refund. I emailed them countless times and AGAIN no response. I don't know how to contact them, i think the only way would be litigation.<br> <br> I need my tablet to be repaired/replaced and i require my refund for the bluespark groupon urgently!
