You can contact us via the our contact form.
Unfortunately we cannot receive phone calls. The reason for this is that we operate on a low margin so in order to keep costs down, we do all communication via email. If we were to spend an hour on the phone with each customer, then we would have to charge a much higher service fee, and we are sure our customers would much prefer to save money and contact us by email instead.
Another reason that we do not accept phone calls is that if you contact us by email, we have a record of the conversation. That way we can make sure the correct item is ordered and your instructions are carried out exactly as you requested. If we did this by phone for every customer, it would be more difficult to track and may lead to issues down the track. We would much prefer no issues which means happier customers. That is what we are all about here at KaiGuys!
The final reason is that our customers are located all over the world in many different time zones. As our business hours are 9am to 6pm Japan Standard Time (JST), then customers in US/Canada/UK etc would have issues calling us as we are in a completely different time zone. Also, if we receive your questions by email, then we can make sure everyone is answered in the order they are received, that way it is the fairest system for our customers from all over the world.
