Hi @ZJanos and welcome,
If you made a withdrawal over a month ago and have not yet received it please contact your bank to request that they initiate a trace on the funds. Sometimes funds can get stuck and need to be moved manually. They should be able to help you locate the funds and get them added to your account.
Going forward I would only recommend opening a claim for an unauthorised transaction if someone other than you made that payment as this is what this option is designed for.
Thanks for your post,
Paula
