Interesting Experience with Billing Concerns

I found the test content engaging and enjoyable. However, I noticed subscription-related charges afterward that I did not initially expect, which led me to reach out to customer service.

Good Test, But Check Subscription Info

The questions were well-designed and thought-provoking. That said, I later discovered recurring charges that I hadn’t fully anticipated. It’s important to carefully review the payment terms before completing the purchase.

Important to Review Billing Terms

While I enjoyed taking the test, I experienced some confusion regarding the billing process. Unexpected subscription charges appeared on my account, which required follow-up with support for clarification.

Be Careful with Payment Details

The test itself was engaging and interesting. However, I later noticed charges on my account that appeared to be related to a subscription I didn’t intentionally sign up for. I had to contact customer support to clarify the issue.

Pleasurable to Use, But Watch Charges

It was enjoyable to take the test and see my results, but I didn’t realize a subscription was included — that part was disappointing.

Good Questions, Unclear Auto-Renewal

The cognitive challenges were fun, but the auto-renewal terms weren’t obvious. I ended up canceling after an unexpected charge.

Not Clear Enough on Fees

I thought this was a simple one-time IQ test, but later noticed recurring subscription charges on my card. The billing wasn’t clearly explained.

Entertaining Test, Billing Issues

The quiz itself was entertaining and challenging, but after a small initial fee I saw charges on my account I didn’t fully understand. Make sure you read the fine print!

`Fun Quiz, Confusing Sign-Up

I enjoyed the IQ questions and the score report, but the sign-up process was confusing and it wasn’t clear what charges I was agreeing to. Watch the payment terms carefully.

Great IQ Challenge, Poor Billing Experience

The test itself was enjoyable and insightful, but seeing unexpected recurring charges on my card made the overall experience negative.
