have a confusion of using come and came in a sentence.
+0
'Came' is the past of 'come'; 'come' is the present and the past participle.

I came home last night.

Every night I come home at 7 pm.

My wife hasn't come home for 3 days.

Use come if the action is not yet completed and therefore it is in the present form of the verb; and came if the action was already completed since it is the past tense of the verb.

You might want to study about the different tenses of the verb including the past, present and the future tense of the verb so that you will be able to determine the appropriate verb for your sentence.
