Hi @Curl presumably you purchased valid product by 30 November. After submitting a claim should receive email notification that it has been successful within 5 working days. After it has been approved the Tablet should be shipped. within 45 Days. However it is stated that need to allow 7 days for Delivery, have you checked your status. https://2021.samsungpromotions.claims/tabS6lite/en-GB/how-it-works
