Why is the speaker leaving the message? [originaltext] Hi, this is Sharon Sta

Hi, this is Sharon Star calling. I tried several times to get through to you at the cell number you gave me, but it has been busy for the last twenty minutes. Anyway, Mr. Trent, I hope you get this message. I’d like to say I’m sorry, but I won’t be able to get to the interview on time. We’ll have to make it some other time.(74)Unfortunately, there’s been a major accident on St. Kilda Road, and traffic is at a complete standstill. There is absolutely no chance of me making it this afternoon.(75)I hope this won’t be a major inconvenience to you. I’m available for an interview any time tomorrow or even this evening if you have the time.(76)Let me give you my mobile phone number again. It’s 777-0045. Thanks.
