Shopify CamXpert **** service

I ordered 4 CamXpert devices 11 June 2024. I queried after more than two weeks and they stated it should be delivered by July and I will soon receive tracking details. It is now more than 10 weeks and still no information nor tracking details. I emailed again this time they state there was an error in verifying my address, my address is on the order, it is even on Google maps, all other courier services are fine with it. Be aware and do not use Shopify nor CamXpert
