Answer:
It means I was compelled to go to town last week.
Explanation:
kompolshan is used to replace compelled in jamaican grammar meaning: Compulsion in english grammar.
It is spelled so differently from our grammar, that it was written toun laas wiik instead of town last week.
Lastly mi is always (that I know of) used for the english term I as in singular one's self.
