Business ProfileforUS MedRehab

I purchased a "NuStep" exercise machine from US MED REHAB in St. Louis MO on in October 2021. With the promise of a 2 week free delivery I was so glad to prepay over $7,000 for the machine. The 2 weeks ended up being 3 months! The first machine was damaged due to the truck carrier having an accident. The company did not come out and tell me of the problem -- after weeks of phone calls and emails inquiring as the where my machine was I was finally told the accident. I let them know that I wanted a different (new) machine delivered. They agreed and it took another 5 weeks for that delivery. Over this issue they also promised an extended warranty to compensate. Upon receiving the unit on January 6, 2022 - it was damaged and we notified them that day and sent photos by email. Another problem developed quickly as they said to go ahead and use the machine -- the arm function seems to be out of alignment or other and isn't comfortable to use. They agreed to order a part to fix the broken piece from delivery and address the arms on the machine. It took until the end of January to work out them agreeing to fix it and how we would do that. They ordered a part and it arrived at our house at the end of February with no word from anyone about how it was to be installed, etc, We called them a couple of times during that next week to ask what we needed to do and no one called us back. 2 weeks ago we called every day Monday through Friday and left a voice mail on 2 different extensions that we needed a call right away to get some direction about our repairs. Last week we just gave up and didn't call them at all. I tried them today and they returned my call off the voicemail. They claim that they couldn't get an order to their service dept. until we let them know that we had the part. We tried many, many times to reach them with no answer, or returned call off voicemail. I asked "**** ********" about all the messages from 2 weeks ago and he said he did not receive them. ??
