Although I agree that a phone call letting you know your blazer was ready for pick-up and possibly a follow-up call when it wasn't retrieved was in order, expecting the blazer to be held for roughly 8 months is unreasonable. Nordstrom Rack (essentially an outlet store operating under the name "Nordstrom") and their alternations department are two different entities. You receive a receipt when you purchase the item and a claim ticket when it is left for alternations and said claim ticket is required to pick-up the item.

I'm sorry to hear you were involved in an auto accident and hope that you have recovered from your injuries.
