Some of the sites that search engines report when you try to look up Roku support or similar may not be legitimate Roku sites. It sounds like you got hooked up with a bogus one masquerading as a legit Roku site. Roku would have zero reason to have you buy a Google Play card, and certainly not to reimburse you for one.
Some suggestions for limiting the amount of downloaded data you use on Roku:
Return your Roku to its home screen when done viewing. If you just turn your tv off, the Roku keeps running in the background.
On any channel that gives you the option, turn off any feature that auto-loads the next program.
Turn on the Roku "Bandwidth saver" function. This kicks in when the Roku has received no user input in four hours. It asks if you are still watching, and if it receives no response, it exits the current stream and returns the Roku to its home page. You can turn this feature on and off via Settings > Network > Bandwidth saver. Note that some individual channels may have a similar feature.
