Question

And you've not yet given me my ticket. (change the voice)​

Answer 1

Here is the correct answer:

And I have not been given my ticket yet by you.

Explanation

The verb in the sentence was in Present Perfect active voice form (have not given). When we convert the active voice of Present Perfect into passive, we use passive form equivalent to the active form. The passive form in Present Perfect is has/have been+V3. The object is made the subject and vice versa; and 'by' is added.

Present perfect active = has/have + V3  

Present perfect passive = has/have + been + V3
