It is a painful experience, but it happens to many people in digital marketing. The first step is to accept it and move on rather than feeling stuck. Look at what little useful information the course or coach did provide, if any, and build from there. Then do your research before buying anything again. Check reviews outside the seller's own platform, look for real results from past students, and be suspicious of big income claims. The lesson is expensive but it sharpens your judgment going forward. What do you think is the most reliable way to verify if a digital marketing course is worth buying?
