Hi,
Post Office don't contact buyer. Use courier facility, they will make a call if the house is confusing.
If you could have sent through courier, they would have given back atleast 50% of money as its not delivered.
The best solution is:
Ask the buyer's exact address, Send them via courier. You may some time need to pay extra costs.
