My trial has ended and I'm unable to add any of my 3 credit cards to my Ring account in order to subscribe. My cards work fine elsewhere on every online website, in store, and I spoke with AMEX who said there were no failed attempts to access my card from Ring, so it's not a security issue. I spoke to the "support" line who simply made me go through the automated phone system to add my card, which also didn't work. They spoke to their supervisor who also said there's nothing they can do. I'm in Canada and the only thing I can guess is that they aren't setup to take Canadian credit cards yet? If anyone has similar problems let me know, and where to go from here. At this point I'm pretty disappointed at this company and how I'm literally trying my best to give them my money and yet they don't want to troubleshoot this issue?
