Duplicate Contacts (Merge Contacts and Remove Duplicates does not actually work)

I have this problem.

Duplicate Contacts (Merge Contacts and Remove Duplicates does not actually work)

I have my contact spread out over mutple source like sim, phone, and accounts.
Problem is each account has duplicates on its own and there has been no cure to this madness.

What can I i do? Merge and remove duplicates are ont actually seeing the duplicates.

Export the contacts to a vcf file, delete all your contacts, edit the vcf file (make them all Account contacts and delete the duplicates) and import the edited file.
