Track SEKO Logistics Packages & Parcels

Bought item from Coggles, who use Omniparcel (SEKO logistics). On tracking the item we found it is blocked at customs in Sydney. We received an email stating “ Due to the customs clearance laws imposed by AUSTRALIA, you are required to pay import duty/tax. Payment was paid via omnipay(SEKO) and another email was received “ Thank you for your payment on your The Hut Group Duty and GST Charges, We can confirm all your formal clearance liabilities for your country have now been cleared for this order.” Issue now is, that the item is still blocked in Sydney, retailer says that custom duties still need to paid and SEKO says they can’t help until the retailer raises an investigation which they had already. With these 2 companies under the THG banner, you would think they should be able to get their acts togethers. Well round and round we go. Totally frustrating
