Experian Credit Reporting Complaint

Experian Credit reporting department,

Credit monitoring or identity protection Problem with fraud alerts Massachusetts

I received - letters in the mail, from Experian and -, respectively, that informed me that an initial Security Alert had been placed on my credit report " at your request ''. I did not request such an alert. The phone number associated with the request ( - ) has no relationship to me and is in another state ( California ). Attempts to reach someone at this number were unsuccessful - the number connects immediately to an answering machine ( my messages have not been returned ). I was able to view my credit report on Experian but there is no way to change the information about the security alert. I will be unable to receive credit for the next 91-120 days because all potential creditors are being instructed, through the credit report, to call this number to verify my identity. I am preparing a letter to Experian but I am not sure how successful this will be. Are there other steps I should be taking?
