Yes indeed. Basically - complaint, company decides not to fight it, pulls the ad, ASA accepts the undertaking.
MTN circumvented a fight by committing to amend the advertisement and promised to ensure that there is no possibility of confusion in the minds of its consumers and the public.
The ASA has a long standing principle which holds that where an advertiser provides an unequivocal undertaking to withdraw or amend its advertising in a manner that addresses the concerns raised, that undertaking is accepted without considering the merits of the matter.
