Interesting. I recently bought an item online for 16,000Baht, an item which needed to fulfill several specifications, from one of the major local online operators.
In the past I've always had good experiences, but this time it was an unpleasant experience, quite difficult to get clear answers and told many times (by the site operator) 'go to the xxx Chatline', which didn't really help, then told 'so go to the yyy Chatline', no real answers, and then a third bbb Chatline, no real answers. Meanwhile being told several times that I hadn't yet paid.
I eventually found the same article on another website (not online shopping) and got all the answers.
Messages to the online operators Customer Service, and Administration center either not answered or answered with just one word leaving me not knowing the full answer.
After many tries I got a live phone connection to Customer Service which produced 'just buy it and it's not what you want wrap it up again (same wrapping materials and return the bed (me return the bed) to the delivery company's office.
Never again.
