old mutual non service

iam not happy at all with the service i got and non service im still getting from old mutual bank division , i have an account with them , then it was frozen and it still is frozen by them , reason being that they cant scan my ID card , mind you this is the same ID i opened my account with them , so i asked for advice and way forward ,they where not helpful at all , so i went to home affairs and told them my situation ,the home affairs officials looked at my ID , scanned it and they told me all is fine ,there is nothing wrong with my ID, so they cant replace it , the gave me also a verification letter stating that iam the owner of the ID , and they took my fingerprints , i took this verification letter back to old mutual and they still refused to assist me , i was sent from pillar to post ,yet i had all the proof that its my ID, and the home affairs have verified it,no assistance nor help nor solutions came from them, i left very angry as my account still frozen ,i cant do anything , withdraw or pay debit orders , i called them and was put on hold for more than an hour , still no solution came , iam frausted now , i dont know what to do, since they seem also to have no way forward, now iam in a rock and a hard place , and i dont know if now old mutual is also home affairs?
