Company ignored my cancellation and decided to ship against my request.
I tried repeatedly after this company claimed they'd made a mistake to immediately cancel the entire offer. This was within an hour after placing the order. Instead, they actually balked and told me they were going to ignore my request to cancel the order and ship it and charge me anyway. I am furious and will be notifying my credit card company to not honor the charge, which was forced upon me, even though I cancelled the order before it ever got shipped.
