Kalahari wont release my paid for goods.

Purchased a television from Kalahari 3 days ago. On day one they notified me that they had received payment (my bank/credit account confirms this), ID copy, TV license copy etc and yet my item is on hold / wont be released. The customer care line said that I had to phone the bank and get a confirmation code and contact either Kalahari or Pay U with that code to approve funds - I did this (although this is the first time I've ever had to do such a complex back and forth with an online supplier), and still my order sits with a big red 'on hold' notice. I'm just not getting through to anybody of significance who can simply just send me what I've paid for - Karl Ahari has ****** me!
