My Parents have stolen my savings?

I'm a "bit" confused. My son has an account of which I am the co-signer, however he can access the account. You said that your mother is "co-signer" of which that would make you the actual account holder "with her just as the co-signer. Now, if the bank says you "the accnt holder" can't access the account, then something seems fishy to me.....I would stop depositing money right NOW until you can get further information.
