High Stream Moving

I booked Highstream to move a piano and was very clear that it would require stairs (with photos and exact count of stairs). At the outset, they sent the quote by text and it included an additional quote for stairs. The movers were polite and professional, however were unable to get the piano down the stairs. They apologized and advised they would return two days later with help to finish the job. This was not a problem - I totally understand that things happen and it couldnt get done. However they never returned, never called or emailed. When I finally had to call myself the person I spoke to said they wouldnt return without further payment. He was incredibly rude and debated me at length about how many stairs were in both homes. In the end they refused to do anything further and I had to hire another company to do the job properly. They still have not responded to communications about another move that my family had booked.
