Amazon India — my international card is not working

I honestly thought I wrote this comment above by Amy Cohen. I had the EXACT same situation. I was using my Canadian card for YEARS.

Off and on it would not work on Amazon.in. Those times I would call customer service.
What was ridiculous that the incompetent staff would not know what is going on and when i would tell them MYSELF that it is due to some international card issue which they seem to have THEN they say 'we do not accept international cards' which would drive me nuts as i would have JUST placed several orders on my card.
I would tell them this. THEN they would say it's at my bank's end. Which would then make me waste my time. Banks would tell me there have been no charges coming through.

Then the issue would resolve itself on its own.
Now for months and months it's not worked at all.

What i cannot stand is that no one there is able to say 'it used to be accepted and not anymore'. No, instead they dont even know that at least at one recent point they DID accept it.
So it becomes extremely hard to know what the issue is.
And how to resolve it .
Because the staff has been kept ignorant, dumb, and incompetent due to lack of communication by upper management.

Amazon is ridiculous. I have spent a huge amount on Amazon and they do NOT appreciate their customers.

Have the exact same issue with a German issued Visa card. It worked once, and ever since it just cancels after having entered the correct CVV. No clue what's going on, bank can't help either. Great...
