in marketing and campaigns, the team has its own strategy for making decisions. If they think that the campaign is less effective, then they have the right to stop the promotion method. If they succeed in getting customers and successfully branding through this forum and then decide to extend the campaign period, of course, this is a different matter. That means the team found a place to promote the most potential and have the right target customers. Is it just wasting money? This is part of the risk in marketing that must be done by the company. All businesses will surely feel that. The most important thing is how they can improve and have the right platform or place to do for the next marketing.
