(CBS) -- Steven Winkler uses Uber all the time and never had a problem until he recently spotted an issue on his bank statement.
"I noticed a $50 dollar charge from Uber."
He contacted the company online and was told he was charged a cleaning fee. They also sent him pictures from the driver of what appears to be a wet seat, but Winkler says it wasn't him.
"There is no way I could have done that without knowing about it."
Winkler is not alone. Social media is filled with upset Uber customers insisting they were wrongly charged for a mess they didn't make.
And the Better Business Bureau tells us they've received more than 130 complaints about Uber cleaning fees.
John McGann and Crystal Drake were charged 150 dollars and were sent a picture taken by the driver but insist it never happened.
"They definitely need a better system in place than what they have," McGann said.
Uber is aware of these disputes and in a statement tells CBS news...
"... We are enhancing our internal processes and investing in additional resources when investigating cleaning fee claims. While messes and spilled drinks can happen in moving vehicles, we are actively looking into reports where fraud may be detected and will take the appropriate actions on those accounts."
After complaining to uber Winkler received a refund, so did Drake.
"My advice for other people would be to take a video when you get our of your Uber," Drake said.
Uber says drivers who submit a fraudulent cleaning fee could lose their ability to drive for the company.
