My two cents:
1. I have a very common name and it seems I did not have trouble because of name check. If I google search my full name it will come out more than 18 millions results. Do not worry too much about name check even if you have a very common name.
2. Making phone call about your case is useful. You may not get right information that you want but it could make your case “alive”.
Your turn will come soon and GOOD LUCK to everyone!
