The Costco member service number in the US is 1-800-774-2678, and costco.com has a contact page with chat and email for online orders. For anything that happened inside a warehouse, the membership counter at that location is faster than the national line: it can refund an item, correct a price and settle a membership issue on the spot. Take your membership card, the receipt and the item with you.

Costco runs separate teams for costco.com orders, Costco Optical, the pharmacy, Costco Travel and the tire center, and the national line will route you between them. Ask for a reference number every time you are transferred, and note the warehouse number printed on your receipt.

Costco takes most items back at any time under its satisfaction guarantee, and you do not need the original packaging, because the warehouse can look the purchase up against your membership number. Electronics are the main exception: televisions, computers, tablets, smart watches, cameras, drones, projectors, major appliances and cell phones carry a 90 day limit from the date you received them. Diamonds above a set weight, custom made items, cigarettes and alcohol are handled under separate rules.

Take the item to the returns counter at any warehouse rather than shipping it back, and bring the membership card the purchase was made on. If a return is refused at one location, ask for the reason and the rule it is based on in writing, then raise it with member service on 1-800-774-2678.

Cancel a Costco membership at the membership counter of any warehouse, or by calling member service on 1-800-774-2678. Costco refunds the membership charge in full at any point in the year if you are not satisfied, and the refund goes back to the payment method the membership was renewed on. Ask for the cancellation confirmation or the receipt before you leave.

Charged for another year after you cancelled? Check which card sits on your account, because a renewal charged to a card you no longer watch is the one people notice months later. Put the cancellation date next to the charge on your statement and raise it with member service before you go to your bank. Start your complaint here at the same time: we open a case and keep coaching you on what to reply and when to push.

Costco corporate complaints go to member service first and then to the corporate offices at 999 Lake Dr, Issaquah, WA 98027, where the company is headquartered. Costco warehouses are company operated rather than franchised, so a complaint about staff conduct, a refused return or a promotion that was not honored lands with regional and warehouse management that corporate can reach directly. Name the warehouse, the date, the time and your member number.

Ask for the warehouse general manager first. At Costco that manager has real authority over refunds and staff issues, and a complaint that skips this step is usually sent back down. Return refused or a promotion not honored? A complaint through our complaint process keeps it moving: we bring your case to Costco through emails, social media and paper complaint letters.

So far consumers reported 10 complaints about Costco here, too few to show a clear pattern yet. Our research shows what typically goes wrong at warehouse clubs and big box retailers: long lines at too few staffed checkouts, membership charges that renew without warning, phone and carrier promotions that are not honored the way they were advertised, disputes at the returns counter, and mobility carts or accessibility help that is not available when it is needed. Staff conduct at the door and at the exit receipt check is the other theme that keeps coming back.
