I emailed support and received this response:
I think reasonable people can accept that there were delays and you might be late delivering, but I'd imagine this guarantee caused a lot of people who would not have ordered in the first place to order your equipment. Please explain how March 2nd can possibly work as a guarantee date for "Early January" orders.
According to the general sales agreement if they are late you are entitled to request a refund ... they already are letting you request a refund with a January order. So while they may not admit to being late - you are already enjoying all the benefits as if they did.
haha.. see customers, this is the reality... not the roses that they waved at you for 6 months
Did anyone talk to you like this last year? nah.. all fluffy promises until the tire hit the road
