This free tool will write you a letter that explains why you should not have been given a sanction and asks for the decision to be revised.
It does not matter how long ago you were given the sanction. You can challenge it now, using this tool to ask for an anytime revision.
Even if you have already explained why you had good reason for the error, it is still worth asking for a revision and (if necessary) appeal.
