Business ProfileforMassMusik

I purchased a new B-Stock *********************** desktop synthesizer from Massmusik on January 28, 2022 through their Reverb.com storefront. The item was described by Massmusik as being in "Excellent" condition, and the single picture of the item showed no flaws or defects.Upon receipt of the item on February 3rd, however, I noticed extensive scratches and gashes on the faceplate. The power adapter and instruction manual were also missing.I immediately messaged Massmusik and told them about the situation. They confirmed that the item had been in excellent condition before being shipped out. They said they would file an insurance claim and asked me if I wanted a refund. I told them I simply wanted the missing items and to have a replacement faceplate shipped to me. They obliged and said they would work to get the replacement faceplate (and parts) shipped to me quickly.I received the missing adapter and manual, but I have never received the replacement faceplate. I've reached out to Massmusik repeatedly over the past four months. Each time, they have strung me along and said that the item would be shipped soon, or that they were waiting for Korg *** (the US distributor for ***********************) to send them the part. They never follow-up on these emails and they never follow through with their promises.I am fed up with the situation and their lack of concern.I want the replacement faceplate and I want to be fully refunded for the damaged instrument they sent me, as well as for the time and energy I have wasted trying to resolve this situation. If they do not do so, I will take them to small claims court for the full amount plus legal fees.I have attached a transcript of my communications with Massmusik. I have also attached my receipt for the item.
