The original thread for this has been "archived" by Laura.
I hope it was due to a particular post using inappropriate language, not merely hiding many complaints for new properties not receiving their postal confirmation codes.
Your address has been fumbled up, you will need to get BDC to correct it.
Most the posties here speak next to no English so that address will cause problems.
Your addy should read;
7 Luang Phor Chuan Road,
Karon Beach 83100
All that Muang, Amphoe etc is confusing the issue.
