I've merged all your threads becaused they deal with the same issue. Please don't keep starting new threads.
If the father lied at a previous hearing, then you ask if the previous testimony can be reread or you get a transcriupt of the previous hearing. You then ask the judge to look over your phone records and confrim that you only received three calls. DO NOT call your ex a liar, just point out the facts.
But I will say, again, that this case is getting complex and you would be better off with an attorney.
