Omg, how do I fix it? Both my phone lines have the same person? Please help, its hard to explain! Flash thingy

Question

Ok, I don't know how to describe it that well but anyway, here's what happened.

I was talking to my bestie on the phone and suddenly I got call waiting (someone else was calling) so like I clicked the flash button to see who it was. So like after I clicked the button I was like 'Hello' and my friend(the one i was talking to before) was like 'HIIIII' and i was 'omg hold on' and she said 'ok' and i clicked the flash again & i was like 'hi' and she was like 'hi!' and then I was like 'omg jamie what did u do?' and she was like 'nothing, u just kept saying hello!' and i said 'omg'. Ok so like I just talked to her for like 30 mins.

But when i clicked the flash button again (i was going to do three way calling) she was still on the line! She was on both lines! Idk how but she was.

And then I got the call waiting thingy (that person calls alot) and well I could never talk to that person cuz my friend is on both lines without a cause!

Also, I hung up and put the phone on its hook, but I

Answer 1

call the phone company

Answer 2

I would call the phone company technical assistance and tell them your issue.  It may be something with the phone lines, it could have been your friend on both (I've been talking to someone, and as a joke, called them from my cell phone as well).  Paying for the caller id may help as well.  This usually isn't very expensive and when the phone beeps to tell you that there in another call, it will show the number calling on the call display (there is also a feature from most phone companies that when it beeps to tell you there is another call, it will actually tell you the name or number calling so you don't have to pull the phone away from your face).
