Half Delivery

Ordered a digital safe and a book safe and a week later the parcel arrived - great service...until I opened the box and only the book safe was in the box. I called Groupon and a phone ticket was opened whereby they apologized and informed me that the supplier was contacted and the rest of the order will arrive within the week. Unfortunately 4 weeks later (e-mails not answered and no feedback on phone calls made) still no product. Really disappointing as I have never struggled before with Groupon. If they can just keep one posted when there is a problem.
