CBRE Receptionist interview questions

Pleasant at first. . Called me back in and said they wanted to offer me the position and I accepted. Said background check necessary. One week later no response, called to check on status curtly told "positon has been filled" and hung up on me. Once crying stopped wrote to HR and complained was told " When they offiered you the positon they were encompassing every applicant" and background check not submitted , After I laughed in there face wrote to their CEO /HR/lying interviewrs and told them I pray they would lose their jobs. With economy my wish may have been granted.
