List z angielskiego. Czy jest dobrze napisany?

Witam, mialabym ogromna prośbę dotyczaca listu z ang. Nie jestem dobra z angielskiego i bardzo przydala by mi sie pomoc, ale tylko sprawdzenie mojej pracy, czy jest dobrze napisana gramatycznie, czy jest sens zdan i zrozumiale. Oto on : Dear Mr. and Mrs. Hi, writes to the State because I wanted to lodge a complaint with the failure of the transaction. Three weeks ago I bought in your own online store denim pants, they are light gray in color printing on the rear pockets. From the accounts of deposit money I had to wait two weeks to send packages. Many times I wrote emails to your company to find out why the package was not sent, but nobody no one replied to my emails. When after a long time expectations delivered the package, it appeared that the pants are slightly different font and color than the order a, what is more, there was one button next to the castle. I expect a refund for the failed sale, or for immediate dispatch please trousers, which I ordered and I hope that this time I will not have long to wait for state response and nice and quiet we will exchange clothes.
