Found in the description of the Warlock on page 105 of the Player's Handbook:

"Sometimes the relationship between warlock and patron is like that of a cleric and a deity"

(emphasis mine)

Furthermore, Fjord didn't "buy" anything. A pact is an agreement, in this case special powers for service/loyalty, and in the eyes of Uk'atoa that pact has been broken. No loyalty, no special powers.
