David's Vending in Burbank, CA They sold me four used junk vending machines, which is $10,000 in 2017. Burbank California

They sold me four junk vending machines in 2017, which totals is $10,000.  I tried to reach them by phone and text, but they are very hard to get hold with.  My husband has to go to their office to demand them to change the machines or refund.  They refused to refund but to bring more junk and problematic machines to replace the previous machines.  It is totally rifoff by this vending company and I need to sue them for my money lost.

I pay $2500 for the coke machine but they replace it with the one valued $500.  This machines was broken down after  a few months.  From the beginning, I contacted them for the bill acceptor bproblem but they never reponded back  Today, I had technicion come to fix and it costs me $575.
