中译英请指教!

我的父亲在几天前跟你们公司的中介约好了今天十一点看房子,可是今天我父亲有点事,所以换成我跟我母亲去看,能不能麻烦你跟那个带我们去看房子的人说一下如果有什么事请打我的电话,不用打我父亲的电话了.
My father had made an appointment with your company to view one of your the properties at 11 o'clock today,but for some reasons,he won't be able to make it.Instead my mother and I will take his place.Would you mind tell your guide that do not ring my father's number but ring my number if there is any change please.Thank you very much.
很乐意能够帮到你,希望会对你有助.
