5 Customer Complaints for Costco Headquarters.
Ask a question, share a comment, review or complaint for Costco Headquarters, here.

  1. Is the customer service phone number the same as the corporate office phone number? I want to contact the customer support department.

  2. It would be great if the company could answer their messages on Facebook. I tried Twitter also but did not get a reply. I suppose I will have to do it the old fashioned way and contact the corporate office phone number.

  3. I have been trying to deal with a problem with my GE washer.
    I have been getting a run around for over a month. Everytime I talk to they have put me off. How and who can I talk to to get an answer? Case 11349424 Member # 111726302640 I have had a repairman out 6 times to no avail.

    1. Still, no one has contacted me.
      Your is not run well at all. I have never had issues with the wholesale warehouses but is another story. People who order from .com need to realize the difference between the two.

  4. Greetings,
    No complaints, I’ve been a Costco member for over 20 years. Just wanted to ask if Costco could consider carrying alternative nut spreads such as sunflower butter. There are many people, including my twins that cannot consume any type of nuts because of severe allergies. I’m surprised Costco has not offered sunflower spreads in its warehouse. You’re missing a large population who would purchase it. Thank you!
