You did harass him and there's nothing you can say to disprove that.
Meaning of harassment:
aggressive pressure or intimidation.
synonyms: pestering, badgering, bother, annoyance, aggravation, irritation, pressure
^ Literally the definition of what you are doing guys, lets not pretend to be stupid lol
Constant pestering/badgering/aggravation/irritation/bother amounts to harassment, if you can't understand that then there's no more I can say as that's literally simple as it gets :S (credit to dandoe for the definition)
