Personal details via telephone????

I app**** for the Explora contract. Karabo helped me with the application.. At the end he wants me to confirm my bank details. I felt very uncomfortable doing so. I asked if there is any other way to do the debit order setup.. I then spoke to Justin, whereby he said I must confirm my full account number.. I was prepared to confirm last 3/4 digits. I told him, he can give me the first half and I'll confirm the rest. I then explained to him that I'm uncomfortable giving my details via telephone. It can be anyone phoning me.. He then very rudely told me that we have to cancel the application. The conversation did not follow after that as I was very upset with the way this is being done.<br> <br> We hear daily of ****s and that we mustn't give personal details.. Do you want to tell me that there is no other way??? <br> <br> How can I be sure that is was Multi choice phoning me???<br> <br>
