Official Website

The Thermos website allows customers to make purchases from the online store and read through customer stories associated with owning a Thermos product. You can read about the technology which makes Thermos one of the most innovative brands in the world. Customers new to the brand can learn care by visiting the Care and Use page.

Social Media

Looking through the Thermos Twitter page and the Facebook page, we noticed several customer service issues answered from the customer support team. The overall feel of the conversations was positive. We even noticed messages of praise for individual customer service agents.

Customer Service Email

The email address listed on the website is a customer feedback form. We sent a message to the customer care team asking for information relating to seasonal returns. The response generated thanked us for the inquiry, but gave no information as to when a customer care agent would respond.

Our Experience

Reaching the customer service department was better than expected. We called and encountered the standard automated system. Although the system provided several options, we were able to bypass the options by pressing 0. By doing this we connected with a customer service agent. The total time to reach the customer service department was less than 60 seconds. The customer care agent answered and by the end of the call ended, our questions were answered. The agent didn’t have to transfer the call t ask questions from a supervisor. We loved contacting Thermos. Can you say the same at the end of your call? Please share your customer service experience with us below.

  1. Bought a new Thermos 1.9litre pump type carafe at Walmart in Wpg.MB.on Friday. On Sat., I made hot chocolate for kids. When I poured it into carafe, the linerexploded with such force that fine glass shards were forced on to my counter-along with a flood of hot chocolate. My kids were very upset & worried & we had a big mess to clean up. I was just so glad that they were not right by the counter when it happened–it could have been a devastating day! What is my recourse?

  2. Disappointed with the new line of thermos bottle. The 40 oz. thermos looks good but now lacks a handle on the cup, the hinged handle is uncomfortable and wiggles insecurely in the hand during carrying, and the screw-on plastic lid expands after hot liquids are put in so that it is impossible to unscrew until it is cooled down with cold water. Such inconvenience!

    I tried to report these things to your consumer line, but after waiting at least a half hour it was a time wasting experience.

  3. Bought a Thermos insulated cup and used for the first time yesterday whilst watching my 10 year old son play football.Whilst holding cup handle came off resulting in hot tea spilling all over myself, dread to think if the children would of been close.

    • Bought 2 THERMOcafe mugs from my local asda supermarket,, both have been used for little less than a week and both have now broken.. thus being the plastic cup inside the steel surround has now become seperared, to reveal very little insulation inside. I’m very disappointed in this product, as I always believed THERMOS to be a reputable brand.

  4. The 24oz Intak bottle lids tend to easily break. Trying to order a replacement through the website or via phone is seemingly impossible. I like the bottle and design but not very durable~!

  5. Please reply with the cost of replacing three (3) lids for product NS402TL4 070511Q. Please advise me as to where to send the check. My address is Pat Lake, 120 Olivia Lane, Ball Ground, GA 30107. Thank you for your assistance in this matter.

  6. I have a SK2020MBTR14 Thermos and the o-ring on the cap is missing. This is a poor design. How can I get a replacement o-ring?

  7. Contacted customer support via phone and email, which I never heard back. I bought a Thermos NS402bk4 and it started leaking after 6 weeks. This is my third purches from Thermos and by far the worst. Very disappointed in the product, customer service and the lack of replacement parts.

  8. Bought a hydration bottle but the seal was missing. The bottle is 2465SSA4 011414D. How can I purchase the seal for this bottle.

    thank you
