How do I speak to a live person if Costco contact number is not working?
It is possible that contact number may become disconnected or overloaded when number of calls is just too high. During such events we recommend to use other shortcuts to get help quickly:
- Connect to a live chat on a Costco website.
- Open Costco Facebook, Twitter, Instagram or any other supported social network and send a direct message there.
- If e-mail address is available send an e-mail. It is possible that e-mail may be answered quicker than getting through a phone support and you will have something in written to which you can refer later in your communication.
