It looks like someone might be using this account

Hi My name is Dylan and i have created this email to try and contact any one that will help me. I have a problem with the account i am trying to access, i would like to remove a monthly payment from the account so that the money cannot be taken from previously used master card. i would like to move it but i can't access my account because every time i try to access it it keeps coming up with a message saying it looks like some one else might be using this account. i am the only one that know's the password and every time i try to answer the questions it tells me i have to wait 24 hours for a reply but i always get rejected. i try to remember the other account that it is linked to but i can't remember any previous accounts i have made before the one i have created.
