How to Build a LED Therapy Device After-Sales Support System
We sold 5,000 LED masks. Then we got 300 support calls in the first month. We had one part-time support person. Calls went unanswered. Reviews tanked. “Great product, terrible support.” Our 4.2-star average dropped to 3.4. Sales dropped 40%. Here’s how we built a support system that restored our reputation.
