Did the British refused to repeal the Stamp Act?

In spite of the petitions' mildness, Parliament rejected them. Bowing chiefly to pressure (in the form of a flood of petitions to repeal) from British merchants and manufacturers whose colonial exports had been curtailed, Parliament, largely against the wishes of the House of Lords, repealed the act in early 1766.

Why did Congress repeal the Stamp Act?

In summary, the repeal of the Stamp Act was successful because Britain realized the distinction between internal and external taxes. Parliament had tried to extend its authority over the colonies' internal affairs and failed but continued to collect duties in its ports to regulate trade and as revenue.
