Hello- is anyone there?

I logged my first ticket with Groupon on 17 December regarding a purchase I had made. I received an email to say my query will be dealt with in 2 working days. After 2 working days I received another email to say that actually it will only be looked at in 3-5 working days. It is now the 5 January 2016 and I still have not had any communication from them.<br> <br> I have since sent follow up emails on the 22 December and 23 December. It has now been over 10 working days and no one has contacted me to provide a solution.
