No delivery bad bad service

I placed my order and paid R1500 with Airydress on the 15 December 2017. Eventually my payment was confirmed by them. Then it was silent. On the 3rd of January I had to contact them to ask what the delay was. They then informed me as follows: We are glad to inform you that your package has arrived. Unfortunately it is detained by your Local Customs and some import duty tax must be paid before you get it. Please contact your local Buffalo to pay it first so that you can get the parcel. The phone number of your local Buffalo is: 0 ********** 01704, and your tracking number is: 905575****** but the number is engaged and then just stops ringing.

Not once did Airydress mention this as an option or possibility. This is ridiculous................
