Campaign terms
There are two campaigns and both work exactly as written here. The numbers on the screens come from live data; this page says what was promised.
01Launch campaign — the first 0 offices get 0 months free
The first 0 offices to sign up get 0 months free. The quota is a real counter: the sign-up page shows how many places are left from live data, and when 0 is reached the campaign closes and later sign-ups do not get it. Once closed it is no longer shown.
02Invite programme — 0 months for both sides
Every office has an invite code. A new office that signs up with it gets 0 months free. The office that shared the code gets 0 months too.
03The reward lands when the invited office makes its first payment
The inviting office's 0 months are added when the invited office makes its first payment, not at sign-up. The reward is once per invited office: a second payment from the same office does not pay a second reward. If a payment is later cancelled, a reward already granted is not taken back.
04Campaigns do not stack
An office that is inside the first 0 and also arrived with an invite code gets the larger of the two — 0 months — not 0. The inviting office's 0-month reward is unaffected; that is a separate reward to a different office.
05Earned months are added to the end of the current period
Earned time is appended to your current free-use date, never written over it. There is no cap on how many offices you may invite. An invalid invite code never blocks a sign-up; the account is created, the campaign simply is not applied. Your own code earns you nothing.
