Hi, maybe you can help. I sent a guitar via UPS Ground signature required. I ship dozens of guitars and always require a signature. In fact, when creating the shipping online, you have to specifically select to NOT have a signature required. The signature requirement is the default. Anyway, MYUPS shows the guitar was "left behind gate". The package was not there and no note was left on the door. I called UPS and they are telling me a signature was not required, but it was. So, the guitar has apparently been stolen, and I am being told a signature was not required I guess I am just out of luck. Do I have any recourse?
