quick update on this
Contact ancestry - explained the issue, the representative could see the issue and was raising a case for review. I was promised I would be contacted which never happened.
Basically lost over 70 matches on thrulines, yeah, I get they may change but 70, nah.
bitterly disappointed with it all
cant trust matches anymore. Had to delete parts of my tree which were put on with matches and records.
After all the money spent, 3 tests and subs for 12 years I'm really disappointed.
