Costco Resolution Reviews

Resolution review

I heard by email from Costco within an hour of posting my complaint. I heard from the manager of that store by phone that same evening. Very productive.

Resolution review

Within 1 hour of sending in my complaint I had a call from Costco Corp. Office. The end result of this issue was a communication issue not unlike the majority of problems in the world. Jason one of the Managers that spoke with me did some research into the issue and resolved it to the benefit of Costco and it's customers. This is Customer Service at it's finest! I felt like I was appreciated and that Jason was genuinely concerned and wanted to resolve the issue which he did. I would like to commend Costco and No No No for the quick resolution. No No No has gained a new very happy customer and Costco has kept a very grateful customer who really appreciates their Customer Service! Thank you!

What is No No No?

No No No is a consumer advocacy website that helps consumers file and resolve complaints with Costco, free of charge.

Our mission is to improve the relationship between businesses and consumers and to advocate for transparency.

If you need to resolve an issue with Costco, you can file a public complaint on No No No and we will deliver your complaint to Costco and ask them to resolve your issue. In return, after you have had your complaint resolved, we will ask you to write a resolution review based on the outcome of the resolution.

The reason we are operating this way is that a) it incentivizes Costco to resolve your issue and b) your resolution review help other consumers more than 'regular reviews' that do not tell the whole story. It is the outcome that matters, right?
