Shamed R&B singer Chris Brown has lashed out at U.S. music retailers who are refusing to stock his latest album following his conviction for attacking ex-girlfriend Rihanna.

The Kiss Kiss hit maker has kept a low profile since the assault in February, for which he was sentenced to six months hard labor and five years' probation in July.

But despite several public apologies over the incident, the controversy surrounding Brown refuses to go away. He insists several major stores are "blackballing" his comeback record "Graffiti," which was released on Tuesday.

On his Twitter page, Brown rants, "I'm tired of this s--t. Major stores r blackballing my cd. Not stocking the shelves and lying to costumers. What the f--k do I gotta do (sic)?"

He adds, "WTF... yeah I said it and I ain't retracting s--t. I'm not biting my tongue about s--t else (sic)... the industry can kiss my a**."

People magazine reports that the retail store giant fired back with the statement Monday: "We are surprised at the comments Online. All Walmart stores nationwide have carried the CD since its release, including the Wallingford store mentioned in the post. This store actually sold through its initial shipment over the weekend. The majority of our stores today are showing they do have copies available."

Brown's Twitter account was shut down Friday afternoon after a final thank you message to his fans.
