I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.
The package was here in Australia from England in a few days โ so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
