Look, I'm not a fan of contravention proceedings when a matter is still in the interim stages, but you might consider filing a supplementary affidavit indicating when phone calls and time spent with events were not facilitated by the mother. You can even leave it until the week or two before the next hearing date so you can have it all compiled into a single affidavit. Make sure you communicate with her lawyer, too, and ask for assurance that the mother will comply with the interim orders moving forward.
If it continues being a problem, then you start deciding whether or not you should request that the child live with you on grounds that it will be the only way the child will be able to enjoy a relationship with both parents.
