One Friday morning, someone called and yelled at me just to tell me i have been calling them for how many times already. I told them i have not and did not since i have not placed any phones calls that day. They told me they have a caller id and the number that was registered is our number. I called PLDT after that conversation on the phone, and they told me that a third party cross line had occurred. As you can see, someone had called them but my number got registered. This might cause a lot of trouble if not address immediately.
