Query: Bluetooth didn't work and software isn't Mac compatible

When I received my phone, the battery was defective. I ordered a replacement battery but still could not pair the phone to anything (I have plenty of experience with bluetooth pairing). Top it all off with the fact that the software only works on Windows, my only option to load phonebook entries into this phone would be manual entry. The interface of the flip phone was something out of the 1990s -- kludgy and childish. The available ring tones are from the same generation. Aside from the technical problems that I encountered, I thought this was a pretty lousy phone.
