Either a wrong impressions count like you said, or invalid clicks because if it was really 135 clicks on 28 impressions it was probably someone trying to get you banned or something. I would email google to be sure before you get banned.
Check in Advanced reports but your CTR is as high as 300% which is something to worry Whether it's 135 impressions and 28 clicks?
Ok, Well I got $7.70 from 164 clicks, So i guess It's updating adn I cannot get banned for that correct?
If you have more clicks than impressions, you probably will get banned. If you didn't make the clicks yourself, send an email to google cuz someone is trying to get you banned
Thats because those clicks were considered invalid by Google and if this continues to happen with your site then you can easily get banned from adsense for life ! BLock the source of those clicks if you are sure they are invalid
ohh thats great that you have received your money , Sometimes happens like this but they update it within few hours . But if you don't get update in one day than do let them know by email .
