I was contacted by support and they have managed to track the issue through their AVS provider down to what seems to be a difference in how Canadian banks report the AVS information; so as soon as I have some time I will try again changing the data and hopefully matching what the bank reports so that the payment can go through. For now it seems Canadian cards have issues going through.
BTW The invoice was deleted to keep the system from retrying automatically.
Thanks to the support person that handled this all the way through.
So I decided to try pixelplow; signed in added my CC and failed, I contacted support and I was told that the address should be exactly the same as the account, so I went into my bank account and copied the address and name exactly as it is. No luck; so then I was told Canadian cards have issues with AVS as they say they provide this feature, yet they dont. I talked to my bank and they do offer AVS and of course I have used the card elsewhere several times without issue.
Long story short, the invoice was deleted from my account and no further effort to get me up and rendering was done, and no further communication, or help from PP.
You seem to be on top of things so you might be able to help further.
Thanks in advance.
Edlo, sorry I didn't see this sooner. We've had almost no end of AVS-related problems from customers in Canada and the UK, but it's actually due to their lack of consistency in formatting of their postal codes. We even wrote up a whole page on the topic:http://www.pixelplow.net/support/why-did-my-credit-card-payment-fail/
Due to the level of problems Canadian and UK customers were having, we were able to soften the AVS checks that our gateway provider makes. They recommended against the changes, but they were impeding progress...so we opted for the nuclear option.
Long story cut short, if you never had anything resolved, it is far more likely to work now than it was a few months back.
