RWO / WENN 1 / 7

Aaron Carter has a website, but it's just not working -- All because of one man who is essentially holding it hostage.

A man named John Cantu designed and maintained the site and spent months building it. The cost of his services: $50,000. How much he's been paid for his services: $0.

Aaron maintains that he doesn't owe John a penny because he was working as an "unpaid intern," TMZ said. John, though, has balked at that claim, saying Aaron didn't teach him anything.

So, John took matters into his own hands, taking over the site he built and leaving it blank. Aaron's team has sent a letter demanding control over the site, but John has yet to turn it over, saying he will do so once he's paid his money.

For now, Aaron is using his social media to promote his music as his website remains in the grip of someone else.

The singer hasn't addressed the website discord, but has hinted at the issue. "There is a sufficiency in the world for man's need but not for man's greed. I rest my case," he tweeted on Sunday. Later that day, he tweeted, "I get mad when I don't get my way."

It's a been a bit of a rough go for Aaron of late. Late last year, fans wondered if he was on the verge of a mental breakdown after posting a very lengthy and very strange letter about a recent breakup, saying his "heart is shattered."

"Has anyone ever had their heartbroken so bad that they feel it in other parts of their body? Like cold feelings in your stomach, emptiness? Love is the toughest thing I deal with in my life," he wrote. "I'm constantly misunderstood and judged for my past, I'm a really sensitive guy and yes jealous and insecure at times cause I know I'm a skinny dude [and] all of the anxiety stuff. [What] I've been through has been about my relationship I've just hid it from you all."
