급해요!! 영어 제발 도와주세요ㅠ(내공)

Dear OO,

My name is OO.

I tried to call you several times to negotiate about our payment but I wasnt able get in touch with you. My mom isnt a fluent english speaker, so she tried to leave some voice messages

and fax with the help of a different person; however, she wasnt able to get in touch with you as well.

I recieved 2 letters from you but the amount declared in both of the letters were different.

One stated for $OOO and the other one $OOO.

I'm sorry to inform you quite late but I would like to finalize the price to $OOO.

I will pay the declared amount at once.

Sorry for the inconvenience, but please let this happen.

I will send you the check with $OOO.

I'm sorry for the delay and sorry for the inconvenience once again.

Thank You.

Dear,ㅁㅁ

Dear XXXX

내 이름은 OO 입니다.

I'm OO

당신과 내 payment 에 대해 상의하려고 여러차레 전화했지만 되지 않았습니다

I could not contact you, even though I tried to call you several times

to discuss about your and my payment.

제 엄마가 영어를 잘못하셔서 다른 사람에게 부탁해서 

음성메세지도 남기고 팩스도 2번이나 보냈지만 아무런 답장이 없어서

이렇게 직접 편지로 씁니다.

My mother is not good at english, Someone who helped my mother

left message and sent fax 2 times but there was not any reply

then i write this letter directly.

2개 편지를 받았는데요 그 편지들 안에 언급한 돈 액수가 틀리더군요

I received two letters but mentioned amount of money was different

하나는 ㅁㅁㅁ달러이고, 다른하나는 ㅇㅇㅇ달러 더라고요

One is ㅁㅁㅁdollars the other is OOO dollars

늦어서 그런건 알지만 ㅁㅁㅁ달러로 해주셨으면 합니다  

I understand that's a little late , please change to ㅁㅁㅁdollars

돈은 한번에 다 지불하겠습니다

i would pay all at the same time

부탁드립니다      (이부분에서요 좀 간절히(?);; please 랑 beg 를 같이 써서 쓰라는데 ..어떻게 맞게좀 써주세요)

Please Help me.

ㅁㅁㅁ달러를 check 로 같이 보냅니다

I will send ㅁㅁㅁ dollars by check

늦은것에 대해서는 사과드립니다

i really make an apology for delay
