Different bill, gotcha.
Do you remember disputing this before? If it won't accept a 'not mine' that was probably the reason you used on the 1st dispute.
Before MOV, call them and see if they will dispute again over the phone. Make sure you get a dispute ID#. If they will not re-investigate on phone, send a written dispute to EX CMRRR.
At the same time, I agree you should call OC and tell them that CA will not remove. Keep it simple and tell them this was not your error and they need to advise their CA to remove as you have already tried unsuccessfully.
If this does not work, you can follow on the next steps which will be MOV to EX and possibly using HIPAA.
