'Come mai mi rispondi?' is an Italian equivalent of 'How come you are not answering me?' Italian language speakers may choose not to use subject pronouns other than for clarification or emphasis. The second person singular pronoun 'tu' doesn't have to be used in this instance. The subject is clear from the verb form, 'rispondi'.
The same verb is often used for "answer" and "reply" (contestar).
So it would be --" ¿Por qué no contesta?"

The phrase 'am no replying back to you' is not a sentence and is not correct grammar.
Thank you for replying = Faafetai lava mo le tali.
A bid in bridge replying to a partner's bid or double is a "response".
If you are smart, you won't. Otherwise, she may just stop replying at all.
