"Melissa" with "Salesforce.com" called from this number.  She had the name of a manager that used to work for our company.  I told her that we were not interested and hung up.  She repeatedly called back, even though I kept hanging up on her.  She wound up calling back a total of eight times!!!!!  Did she think that after the 5th time I hung up on her that I would pick up on the 6th 7th or 8th call?!!
