Shockingly terrible service

The most horrible service EVER. My parcel arrived in SA about three weeks ago and to date I still have not received the custom invoice nor my parcel after sending endless emails. All they keep saying is that the invoice will be sent shortly and at this point I think my parcel might even be lost. This is so frustrating honestly as I need the goods urgently. This is not the first time I’m dealing with this company and the service gets worse each time. They lack professionalism, customer service and urgency. This company doesn’t deserve to be in business honestly coz the service they are claiming to give is non-existent at all.
