Hi,

Could anyone kindly check and correct my sentences below?

"I believe my mom has told you that I have posted the mail off by DHL. It will be arrived to you hopefully within three to four days. Would you be able to extend more time for us given that I am now in overseas? Thanks"

Many thanks in advance guys!
