Delivery never received

I too was ****med by the so called closing business in Camps Bay. Bought and paid, they said it will take between 5 and 14 days to arrive. I followed up constantly and a month later, the so called package was delivered. No one knows which company it was delivered to and some lady named Sandra signed for it. Now, the courier company wont take responsibility and Maria Jewellery dont know their ass from their elbow, cause "its not their fault"? According to them it was delivered and that's it. What to do, what to do..... If I could give no stars, I would, how can people be so unhelpful and take people's money without giving it a second thought? I hope this issue is resolved and I get the ring I paid for.
