Fans of Atlanta rapper B.O.B. were left upset, after the rapper was a no-show at an event in Duluth, Georgia.

According to the Duluth News Tribune, B.O.B. was billed as the headliner at a show at Grandma’s Sports bar.

The show, which was promoted by Neuro Blast Entertainment and Kavari Lyric Productions, also featured a performance by Atlanta rapper Young Dro.

Fans had paid as much as $25 to see B.O.B., after commercials for the concert were aired on local radio and flyers were passed out promoting the show.

According to the promoters, who downplayed using B.O.B.’s name to promote the concert, the world famous rapper could not make it to Grandma’s to perform due to flight problems in Detroit.

At press time no refunds are being issued to disgruntled fans who were duped out of a concert with B.O.B.
