I bought a brand new Keurig K-Duo Plus coffee maker November 20,2021 at Bed, Bath and Beyond. After six months the coffee maker stopped working. When I contacted Keurig support via phone, after a long wait, I finally was connected to a rep who spoke very broken English. He provided me with a reference number. There were several emails back and forth with the required pictures and information. I was told then that the proof of purchase that I had provided was not acceptable and that I would have to produce the original receipt. I explained that I no longer had the receipt.
I received a return email telling me that without the receipt they would not the honor the warranty. I asked the rep if they had the warranty registration information on file (what is the purpose of the registration if they don't have it on file). They will not answer my emails or phone calls The product reliability and customer service speak for themselves.
Don't waste your money!
