Accuracy gaps

Despite a 98% accuracy claim, data is often incorrect. Emails, phones, and contacts are outdated, leading to wasted credits and inefficiency.

Clunky interface

The intent list is hard to search, and there are too many phone numbers to choose from. This makes finding the right contact more difficult than it should be.

Questionable policies

60-day cancellation policy locks users in with little notice. Downgrade options are limited, and support offers no help with avoiding renewals.

Missing info

Significant portion of the data is outdated, with 20-30% accuracy, leading to inefficiencies and wasted credits.
