Ordered something, received an email saying there is a delay for the items, will arrive the next week. Next week comes, received another email it will take another week, cancelled and requested refund.

Being told that the item is delayed a day before it's due to arrive, with an email saying it hopefully should arrive 6-7 days later, and then again another 6-7 days, really holds up my sites, and becomes detrimental to my business.
