Your non-standard formatting makes it hard to read the logic of your code, but

I think that you need to remove this from inside of the loop over all contacts. The very first return statement your code encounters forces your function to stop. This needs to go somewhere else in your code.

It really helps readability to indent your code.

for (some loop head stuff) {
  if (condition) {
    do something;
  } else {
    do something else;
  }
}

Edit: ahhhh, I see now. It looks like you copy-pasted another solution inside of your function. I strongly recommend against doing that, as it will make it harder and harder to solve these challenges.
