These are very rare situation and our team may definitely look into the cause of this. There are different scenario that may have happened:
1. Change of address was requested and order was shipped to the new address.
2. Change of address was not able to get done before fulfillment and order ended up shipping to original address.
3. A tracking # error in the system that provided you a wrong tracking #. Although this rarely happens, but we can definitely locate the correct tracking # for you asap.
Please feel free to contact us and we will investigate your shipment asap.
