Why my total earning is not equal to sum of all monthly earning.

I received a cheque from adsense last month through standard delivery from the previous month on reaching $100.
Now my May earning is $20.
As that of June is $30 so far, when you click on since last payment it shows up $38(at present) and its always $12 less than the actual which it should be when calculated per month basis.

I want to know only few things.
1. To whom to contact for reporting this ?
2. Why is it showing up $12 less all the time ?
3. Any Idea or help from your side?

Regards,
Yogesh

 

Was your payment processed part way through the month? My 'May' check was processed on June 22nd, but now June's earnings only show earnings since 22nd June. I think it's just a bug, many other people are experiencing things like this.

 

yes, I am also facing the same problme...
I guess it is a bug....

I send adsense team an email in the morning about this issue...
but I guess it is a bug, since I am not the only once facing this problem

 

It's a bug, I guess it will be fair in the end of all.

 

Same experience here...

 

Oh God....Thanks mates....I thought its happening to me only but it seems problem for everyone here.

 

Big problem. I confirmed.

 

Thanks mate for all your support. Now everything is rectified.
