I bought Tier 3 (5 LinkedIn seats) and later paid $237 for 3 more seats after Sendpilot's own team offered them via email. The extra seats were never added to my account — still shows 5, despite three follow-up emails with payment proof over a month. On top of that, 3 of my 4 previously connected LinkedIn accounts disappeared from the account entirely this week, with no explanation. The core product works fine when it works, but support on billing/account issues has been very slow.
