BB Bold :: Contacts Duplicate Itself?

It was fine until Monday when the contacts did it again. It also deleted all the information that was added to each contact (like facebook, email, picture etc) and defaulted itself to a standard work number. It would show doubles of some contacts, three of others, and some even four. I then went to AT&T and they just looked at me like I was stupid, saying that it was because I synced my phone to my computer. Well for starters, I don't have an address book on my computer, and I don't know how to used outlook. Also, I've synced my phone with my computer several times before with no issues.I then went home, called AT&T and the Blackberry Department and still nothing. They said it was all a syncing issue. So after all that being said, I re-deleted the extras and re-organized a few.

Today I noticed that when I linked one of my BBM contacts (she had gotten a new pin) to her contact info, the address book again duplicated itself. So I am guessing this is the problem? Is there away I can link BBM Pins to Contact Info without it duplicating all my contacts and deleting their other information? I'm really crazy when it comes to organizing, and I can't keep having my contacts getting messed up continously.
