Wendy Jones, 32, of 46 Austen House, Cambridge Road, West Hampstead was due to stand trial at Willesden Magistrates Court today.
However the prosecution's principal witness, the office receptionist, did not appear and no evidence was offered.
Jones was found not guilty of sending an offensive, indecent, obscene or menacing message to 156 High Road, Harlesden on March 30.
Outside court she said: “Jeremy Corbyn's sorted that out,” claiming she had spoken to the labour leader about the case.
Prosecutor Miss Dilichi Onuzo told the magistrates: “The complainant works for the MP's office and three calls were made making threats to her on the same day.
“She does not want to attend and wants to make a withdrawal statement.”
