Request for removing the comment of the phone number

Had a number of missed calls coming from this number. By mistake returned the call and got through to the answering machine which said it was some financial services. Hung up, checked my mobile account, which showed no charge was made. Nonetheless, called the mobile provider, they confirmed that no charges have been made so far, but put a note not to charge anything in case payment demand comes in in future. Hope, it all works ok and without any losses.
