Lack of proper communication channels

I have ordered a few things. I received a call from my bank that several amounts were going through my account and it looks like *****. I did not know what these amounts were and my card was cancelled as I suspected *****. Amazon has deducted 3 amounts but I do not know for which products it was as I can only see 2 products they are shipping to me. They only have pre-programmed limited answers and you cannot call them as they do not make provision for a South Africa number. I cannot get hold of them to resolve the issue and I do not know if ***** was committed on my card or if it was one of the products. It is so frustrating. Previously it was so easy to order and communicate with them. It is a nightmare now. If this is how they work I am never going to order through them again.
