In February of 2023, I ordered a Course (DVD and book). It was my first time dealing with this company and one of the incentives for me was their 365-day money back guarantee. The purchase was practically risk-free. Because the course was not what I envisioned, I returned it (via USPS, with tracking) and it was delivered to them on May 22,2023. Initially, they told me the refund process would be about 3 weeks. Then, it was 4 to 6 weeks. The latest is that it's 6 to 8 weeks. The reason they gave is that they are migrating their database. But, suspiciously, the migration process isn't affecting their INcoming orders, only their OUTgoing refunds. So, 8 weeks after my return was delivered to them (as proven so by USPS tracking), I'm still waiting for a refund. And each time I call them (because emails do not get responded to for days - and I can prove that as well) to ask about the status, there is an excruciating long wait time (average is about 16-23 minutes on hold). As stated, this was my first purchase from The Great Courses - and probably my last. 365-Day Money Back Guarantee? Sounds good in theory but fails miserably in practice.
