Bonjour j'ai besoin d'aide pour la correction d'une histoire en anglais MERCI ( moi aussi les stabilos je n'ai pas compris parce que ma prof à mis les prétérit

Bonjour :)

Today I will tell you one of my creepiest nightmares:

A young girl who was saving for university started to watch a neighbor's house in order to earn some money. The neighbor asked her to come by 7 pm.

She has been home for an hour when she received a phone call. The man on the phone told her that if she didn't leave the house, he would kill her. She hung up and tried to find the identity of the caller but she realized he used a private line. Thirty minutes later, she received another call. ''If you don't leave the house soon, I will kill you'', said the husky voice on the phone. Once again, the girl hung up and called the operator, asking how she could trace the phone call. The operator suggested her to keep the man on the phone for a minute in order to be able to find the phone location. The man called a third time thirty minutes later and this time the girl replied and asked him some questions. He told her several time to get out of the house before he came to kill her. The operator called her back, panicked. He told her to leave the house immediatly, because the call came from the second line of the house. The one on the second floor. The murderer was in the house.

J'ai corrigé comme je pouvais. Il n'y a pas de s quand on parle au passé. L'histoire est un peu confuse: comment l'opérateur a le numéro?
