Theft or Estafa? Pls help.

Hi! greetings to all po, my wife worked in our home owner's assoc as a volunteer, after several months she stopped with advice po sa president ng HOA. After few months, nagkagulo then some people took over the admin office and appointed themselves w/o the president's approval. Yesterday, they sent a letter demanding my wife to explain due to non remittance of payment/ORs she signed previously. It's just a letter with OR numbers. I want to ask if these ORs can be really used against her by these people? If so, is it theft or estafa?

I read the revised penal code what do the following mean under estafa/swindling? there should be money involved?
(a) By using fictitious name, or falsely pretending to possess power, influence, qualifications, property, credit, agency, business or imaginary transactions, or by means of other similar deceits.

BTW, my wife didn't sign the letter but we have the copy. These people who took over po are doing this to use my wife against the president. They're asking for a signed statement. At present, the HOA president filed a robbery case and attempted murder against them. Please enlighten me as to what case can we file against these people po. Thanks in advance and God Bless po.

Mga sir pa help naman po. Thanks

your first concern should be how to prove that your wife actually remitted the collections.
