Bests & Worsts Reviews from Amazon

Part 1, I received the bench and used it for about a month while building my new home. It broke after I moved. I contacted Northern Tool and Equipment and they very kindly said they would ship out a new one to me no charge and requested I send back the old one so they could see the design flaw. 2 weeks later I still did not have the table they said they shipped so I called and they told me it was returned to them because THEY shipped it to my old address and not the new updated address I very specifically in writing told them to send it. The new address was at the time of exchange and is the current on file address with Amazon. They then said it is against amazon policy to ship a replacement to my new address and argued with me about the semantics and logistics involved. Part 2, I filed an amazon A-Z claim and Amazon returned my purchase payment to me (end of story right... not even remotely) Part 3, 2 months later I receive a letter from a collections agency (JNR Adjustment Company based in FL) telling me I have an outstanding debt in collections from Northern Tool and Equipment and they are trying to collect on it. Northern tool without ever having felt with me directly and never providing me with an invoice or bill or goods decided to send me to collections. This is disturbing because of the potential significant impact on my 800+ credit score. I reached out to them and they told me because Amazon refunded my money and I did not send back the table at my expense I owed them the full price. Part 4, Amazon sends this letter on my behalf "Hello, We've been contacted by a customer regarding the order identified below. -------------------- Order#: 111-xxxxxxx-xxxxxxx Item: Keter Folding Compact Workbench Sawhorse Work Table with Clamps 1000 lb Capacity Reason: seller fraud Details: Northern Tool + Equipment, Customer has been sent a letter by collections agency. This is fully against Amazon's seller policy. Please immediately remove all collection requests against customer. This has been reported to our team for investigation. Please provide immediate resolution. Part 5, No response from seller as of yet but now I have wasted about 5 hours of my time with this.
