Переведите на Английский язык грамотно письмо, пожалуйста

Я могу предложить такой перевод:
Dear Sir/Madam,
I have got an extract from a statement of my bank account, it acknowledges the money transfer for the purchases in your on-line store from my bank account onto yours. In case you do not deliver the purchases to my address within the next few days, I will appeal to the bank, the police and the Interpol charging you with a fraud.
In that case the purchases will not be accepted by me but I demand a full refund.
Но откровенно говоря, глуповатое письмо получается. В Интерпол, к примеру, не могут обращаться частные лица. Банк может предоставить документы об оплате, но он не будет ничего требовать от этой фирмы. Полиция примет заявление, но если сумма покупки небольшая, то, конечно, никто не будет обращаться в Интерпол. Разве что таких заявлений будет много.
Успехов.

Hello.
I have an extract from Bank that from my account into your account money for my purchases in yours the Internet shop has been transmited.

It is possible to change words and offers in transfer, the main thing that the sense would remain this.

To donkeys with transfer from Google, промта and other automatic translators, the big request not to answer!
Fluderstam with "clever" remarks as the big request not to answer!
Many thanks for the help!
