Multiple Duplicate Contacts & they keep growing

I've just noticed that a whole bunch of multiple duplicate contacts have appeared in my Z10 address book and they appear to be increasing in numbers like rabbits.

Some of the entries are full & complete copies whilst others are just the contacts name with no other details.

Having looked through the contacts that have duplicated I can't find a consistent common element ie some have Facebook, some have BBM, some have LinkedIn, some are Gmail, some are Hotmail, some are combinations of the above whilst some only exist in one place yet keep duplicating.

I've tried deleting the problem items but they keep returning after a few days. Likewise, linking doesn't help.

Have searched the forum and seen some success has been achieved by turning off 'syncing' from the various apps, sim and email accounts but this 'fix' doesn't appear to be working for me.

My address book is now showing 462 contacts, the correct number is probably nearer to 200.

Help, anyone!

Thanks, Dave.
