英语翻译今天UPS答复我,系统显示你已经收到这些包裹了?你怎么说没有收到呢!你为什么这样做呢?

According to USP's reply to me today that you have got these parcels.But you told me you haven't got them.How could you say you didn't and why did you do like that?

Today UPS answers me, the system demonstrated that you already received these packages?how did you say that has not received!why do you do this?

UPS replied me today that the system confirmed that you have already received the parcels.How come you said you did not receive the parcels?Why did you do things like this?
我个人认为语气不太友好.要是我就这样写：
UPS replied me today that the system confirmed that you have already received the parcels.Please check with your colleagues.Maybe someone else signed for you and forgot to pass the parcels to you.Considering our good relationship,we are hoping to have your positive friendly response very soon.Your cooperation will be highly appreciated.
今天UPS答复我,系统显示你已经收到这些包裹了?请咨询下你的同事.或许有人代你签名却忘了将包裹给你.基于我们的关系,希望你能尽快核实,并将积极友好信息及时反馈.
