I had a failed transaction as I did not have enough funds in my debit card so I called to let them know that I have now topped up my debit card and to find out what is the process to finalise the transaction once I now how the funds in the card for that previous order, and they had no idea what I was talking about.
They discussed the times they processed the transaction and it bounced - all while I was asleep and could not resolve the issue.
Then they discussed all the reasons transactions fail with banks and the time it takes for processing a newly added card onto my account.
Oh my god, it was like talking another language. Amazon do not have a complaints department to speak to someone who can understand what you are asking. I had to cancel my order as I could not get a straight answer for what is the process for finalising an order previously placed once the debit card now has money in it? They will discuss anything but respond to that question.
