Hi, It looks like your issue is with the performance of actual Sendle shipments rather than the integration functionality supplied by us (Joovii) as developers of this App. We have reached out to Sendle with your store details and our contacts there have committed to contacting you to solve the pick up / delivery issues you are facing. As a Sendle customer myself I can attest that the individual courier drivers are excellent 99.9% of the time. If my assumption is correct and it is Sendle that you are disappointed with rather than our app, we would appreciate you reconsidering this review and to rate the app accordingly with the performance of the app alone. Thanks, Team@Joovii
