So I'll try to keep this as short and simple I'm a DV survivor and my daughter's dad hasn't seen her in nearly 2 years and we have a restraining order preventing him knowing our new safe location but CMS handles a case on my daughter's behalf where they take money directly from his wages to pay her expenses this has been going well recently but yesterday I got a random email saying the account has been shut down! I'm the only one with access to it and the only other person who knows about it is her father I called CMS who told me they were sorry but a letter with the account information was sent to our old address shared with her dad and not mine the woman on the phone was very unprofessional when I explained my ex must have used the letter to close the account and save himself the money she just said I'd need to reapply for it but it took 2 years just to get the payments in place in the first place 
what can I do next in this situation surely it is fraudulent and he's controlling me indirectly by doing this ?
