Follow up with BIG apology
Further to review below...the duplicate contacts are only appearing in a contacts app I added to my iPhone, that app is not working so well because Im using google synch etc and its pulling contacts from various sources I use....
THIS app cleaned my duplicates on my iphone very well, plus tech support got back to me within 24 hours.
Good app Id recommend and sorry for complaining before I checked!
