我直到现在都没有收到回信.翻译成英文

receive your letter 是你“回信”给别人的意思，不是说“收到”来信

第一个人用对了hear from，但是为什么要在now前面加个until？好多余，直接用now就好了

I haven't hear from you now.

i don't have your feedback so far.

I until didn't receive a letter in reply now

I haven't received your letter up to now!

I haven't received the letter so far.
