You’ll be charged your subscription fee for Boost every month in advance.
You’ll be charged your first monthly subscription fee the same day you sign up. After that, you’ll pay your subscription fee every month in advance on the same date that your tenancy started (except for the first month, which you’ll have already paid for).
If you want to take out another Boost Subscription, you’ll be charged your monthly subscription fee on the same day that you already pay for your existing Boost Service(s).
You can see a summary of all your monthly payments in your account.
