I prromise to call back - that was a week ago

Groupon referred me to Dawn Wing as they advised they had delivered both the items I had ordered. <br> <br> I called them and gave the reference numbers that Groupon gave me but they said they do not exist. I spoke then to Rageney (I apologise for the spelling) and was advised last week Tuesday 15/12 and was promised to come back to me. Yesterday I phoned twice and left two message but no one phoned. Called in today and was advised she was not in and they would put me trough to the person who assist her however the call was dropped.<br> <br> PLEASE SOMEONE DO YOUR JOB AND ASSIST I am so angry
