Used it but had concerns. Quite a few phone numbers came back disconnected. Asked support how to flag the closed-storefront rows.
Genuinely sorry the data wasn't up to standard for you, we'd like to dig into the specific rows that failed and refund or re-export them for you. Please open a Support ticket from the Help menu — paste a row sample of what failed and we'll credit those rows or re-export the file from a fresh pull.
