It is a well established fact
that your ex is a windowlicker of the highest order. I doubt she will ever respond to reason or appeals to her better nature. She has no legal or physical basis to deny you this access and is probably only saying it because she knows full well you cannot afford to take her back to court. Even if you did take her back to court, is there any guarantee that she would comply with any further court order? She frequently cancels or changes your visits now - she's basically got your balls in a vice with this one.
However. Can you prove that you are giving her maintenance money, and that she's a benefits fraud? It could well be that a threatening solicitors letter may scare her sufficiently to get better access.

EDIT - is there no way you could expose her as the lying, cheating, scrounging lunatic she is and get sole custody?
