Hello Deer,
Kit just went through all our resellers and listed the ones that have an IT shop in one of the IT malls in Bangkok. You can find his list below.
He also checked the 4 shops you mentioned and only found one to be our reseller. The name of this reseller is Cybercom. The 3 other shops are not our resellers. See the email from Michal.
Looking forward to hear from you how you're doing.
