I cannot access my funds

I have been transferred from one branch to another and no one seems to have a solution to the problem. I am told that my signature is not the same from when I opened the account and I need to use funds from my account. I have provided id copy,license and everything one can think of. Now what happens when I cannot match a signature I had years ago???? I'm sure no ones hand writing is the same as it was years ago. Can I get someone who will speak sense to me and sort this out
