Hello,
I hope all is well with you. I spoke with my friend last night and we talked about his move. He moved 6 months ago with an international movers named Siam Relocation. He told me that the service was professional and reliable and mainly they were cheap hihihihi
. They have an office in the center of Bangkok, so you can meet them directly to request more information if you wish. I checked on internet i found their website, you can check by yourself:
http://siam-relocation.com/ . He was in touch with a salesman named Jonathan and apparently he was very prompt and kind.
You can contact me privately, I could put you in touch with my friend, he will be able to give you further information and mainly his feedback regarding this company.
