I had a missed call from Google a day before yesterday while I was sleeping. I called back and it was from Google. I asked them if it is Adwords department but they said No and they were also not able to tell me that who and why someone was trying to call me because it was a common phone.
I do not work for any big company, am freelancer and have Adsense on some of my websites for 2 years now. Never received a call from them. Isn't it strange.
Any one had same experience, please share and if possible, tell me what could be the issue/whatever. Thank you
