Your SixLeaf is account is necessarily linked directly to your Amazon MWS API.
When your SixLeaf account is cancelled (either as a result of a request to cancel or due to failed billing), the MWS integration is unlinked.
When this happens, our ability to automatically verify orders and issue rebates for an ongoing campaign ceases.
Therefore, any active and ongoing ZonBlast Next Rebate campaigns are necessarily paused.
When you come back, the campaigns will be ready to restart.
