3MReviews on record for mmm.com

The products were completely messed up. & it was very late getting here. Plus the company will not replace the products or refund me

This is the first time I have been driven to social media to say how bad a company's customer service has been. I bought a 3M air purifier which is important for the health of someone in my household. The indicators started giving strange signals, not covered in the operating manual. I have been trying for weeks to get a comment from their customer service team, but am either ignored completely or get an answer to a totally different question, despite asking the question over 4 times. Appalling customer service, especially when I have highlighted the potential health connection to them.
