Thanks, I've emailed them 3 days ago so regardless of the time, I feel any response - even just thank for your email we'll respond with 24 hours - would be reasonable.
As for the delivery guarantee, that's fine and understandable but if they can't meet the deadline or guarantee, I'll need to cancel the order ASAP as I'll be in Japan for 3 months so it's imperative that I get in touch with them ASAP. I just have some very basic questions that need to be addressed and a very tight window of time. I've sent 3 email so far (1 per day) and if I don't get a response by Monday, I'll need to cancel the order. I feel that any clothing maker offering MTM or custom services ought to have a direct telephone number to contact.
