First, I am baffled about how, if you never met the person, you think it will be difficult to avoid violating the restraining order.
Here's the problem: there are RULES about how to do things LEGALLY. If you follow the RULES, which actually do follow a pattern of reasoning, the court will favor you over someone who doesn't follow the rules - even if your argument kind of sucks.
You DID NOT follow the RULES: you did not show up, and there was no "motion to continue" (postponement) filed on your behalf. So, there's a "default judgement" granting a restraining order against you. Your "written rebuttel" has scant weight, no matter how valid your reasons. And yes, you probably could have made an effective argument if you went about things correctly.
As you seem to be ignorant of how vast your ignorance is, you would be better served to go into debt hiring a competent lawyer than doing anything pro se (representing yourself without a lawyer). If the other persons claims are silly enough, you can even sue for legal fees.
