Sorry to hear there has been a delay in shipping your replacement Clip+. This is more the exception than the norm. Warehouse reorganizations happen from time to time, they should have it sorted out shortly for you.
Did you register your device with SanDisk? If so, you can track your status online. In any case, especially if you have a case number handy, you can call 1-866-SanDisk for status updates.
Over the years, replacement devices and support have been handledthrough different locations, so the time can vary a bit. I have had a replacement device in about five days after running through the system. Shipping from my end to SanDisk took two days.
