If the Terms end before the end of a paid billing period — when you close the account, switch to another provider or ask for erasure instead, and when we end the Terms, on notice or for cause, or discontinue the Service — a Business Customer is not refunded the fee for the rest of a paid billing period. This is the only charge connected with ending the Terms early. Details: Refund Policy
