Theoretically, the colonists WERE represented in Parliament. In the US, we're used to the idea of one representative from our district representing us. However, British legal doctrine of the time had an idea called "virtual representation." While MPs were elected from their districts, they theoretically also represented the interests of all British citizens, including those in the colonies.

As a practical matter, of course, the colonies had little to no representation. There were MPs who supported or were sympathetic towards the colonies. Edmund Burke, for example, staunchly supported the colonies in Parliament. He introduced several resolutions and made speeches supporting the colonies, and one of these resolutions would have given the colonies parliamentary representation. So did Parliament consider giving the colonists representation? Yes, in that they had to decide how to vote on Burke's proposals.
