Google has debited $7.01 from my account for no reason!

Hi, I am user of Google Cloud Platform, I have set up billing option couple of days ago for Cloud build API, I have revised that there are 192 build minutes are free

and my build history and minutes calculation is listed

now google has debited $7.01 from my account for no reason! I have not used any exceeded any free limits, still why my $7.01 were debited please would you mind to take a look at this please!

I am student and I can not afford this $7.01 because I was just using Google Cloud for Learning with lowest possible resources consumption please make sure to credit back my $7.01 I will never use this platform.

Hi You can raise concern and sure they will refund if wrongly billed.

Hi,
I highly suggest to review billing raport for project, where builds were run. It will show, which services costs.

best,
