I experienced a different issue. I kept receiving different phone calls from 650 2345 xxxx numbers. (650 2345 are made up) the first 7 digits are the same as that of my number. only the last 4 digits are different. normally I won't pick up. But some number kept calling and I received this kinda of phone call quite often. So, one day I picked up, on the other side, it was an angry lady asking who I am, and why I kept calling her. I said I didn't, I was just picking up her call. She said "stop calling me again!" then hang up .... Then I emailed google about the issue. they seemed to fix for a short period of time and then it happened again. I switched to t-mobile then.
