The problem is 2 fold...... 1. Seller sent a product that had not been properly assembled. This wasn't clear until I attempted to fix the issue. Seller was contacted about the issue and would not take it back because I spent hours " fixing " what should not have needed fixing. After some text messages they offered a partial refund or credit towards another instrument. When I chose another instrument that was posted, they stated that it was not available. Further contact has been ignored. 2. When I attempted to get EBAY involved with this, every attempt was ignored! Have not been able to have any dialogue with EBAY no matter how many attempts have been made. So far EBAY is batting ZERO in the customer service dept. Anyone else with issues like this?
