OP here. This is getting to be a serious problem now, with me already having left home on my positioning flight (my RJ flight starts from the Middle East).
I called the NYC office of RJ (assuming they are the biggest in North America) and was told to contact the Internet Booking department in Amman. Sent them a message and they replied AFTER FIVE DAYS spitting out the same garbage (in the very same words) that is there on the RJ website. They want a "virtual number certificate" - but there is just no such beast. My bank, and I presume all US banks are the same, has no paper "certificate" for any virtual CC, let alone for each and every virtual number!
I wrote RJ that I have the original credit card bill showing that my account was debited for the RJ ticket, but the zoombie who responded ignored that and insists for a "certificate"
Now what do I do?
