An unnamed individual then called round to the house where Mrs Zaghari-Ratcliffe is being held.
The family refused to allow the individual into their house as they recognised him as one of the IRGC officers.
The IRGC took the British national to court to face a second set of charges two weeks ago.
Mrs Zaghari-Ratcliffe complained that only the tagging centre and not the IRGC has the authority to monitor her movements.
She was determined to not be intimidated by the IRGC individual.
She said in the report the judiciary was required to talk to the IRGC, and not her.
Mrs Zaghari-Ratcliffe urged the Tehran deputy prosecutor Amin Waziri to contact her directly instead of through the IRGC.
The tagging office said there may have been a technical problem which her tag which caused the IRGC to call at her home.
Mrs Nazanin Zaghari-Ratcliffe was apprehended by Iranian police at Tehran airport on April 2016.
She was travelling home to London with her young daughter.
An Iranian court sentenced her to five years in prison for allegedly plotting against the Iranian government.
Mrs Nazanin Zaghari-Ratcliffe maintains her innocence.
