Kid presses button on app, $900 down the drain

(CNN) - Kayla Howard's house is a lively one. A single mom working two jobs to support her four kids.

"It's been a struggle. It's been a challenge," Howard said.

A challenge often eased by technology.

"As you can see, they all like their devices," she said.

Their favorite app?

Roblox.

The popular online platform where users can develop and play games. Users can pay to upgrade their character or buy additional games.

But a source of fun in Kayla's home has become a source of struggle for her.

On Saturday, as her son was using the app, Kayla got a call from her bank.

Several charges from Roblox totaled $897.

Kayla's account overdrafted.

The money she was saving for gifts, decorations, and rent was gone a week before Christmas.

Right away, Kayla reached out to Google Play and Roblox.

Google refunded her just $10.

Kayla filed a claim with Roblox and is still waiting to hear back.

A spokesperson said they evaluate and refund unauthorized purchases on a case-by-case basis.
