RMA Processing Issues?

This is now Day 5 of trying to get my credit card info entered and call #4 to Netgear Support purely in this regard ouwith the original technical issue. 

I have just concluded with Agent # 5 in the course of this call, which has already been 2 hrs at this point of writing! 

It is not being declined, says invalid information 

Have tried 5 different browsers over 2 different platforms 

This current tech sent me a direct invoice - same as tech at beginning of week did and tech earlier in the current call - but still involves completing essentially the same form and fails at the same step

During the course of the call with Agent 5, I called my bank on another line checking on my preferred card status - they validated it was active and further checking said that no inquiries had been placed on it in the last 24 hrs - again validating it was not being declined by the bank.  

I did not get anywhere - they finally said would escalate to "engineering" to find out why it would not accept the input, either at my end or at theirs. 

So now I am waiting for another call back from 'engineering' 

I cannot possibly be the only person having this issue with the credit card validation????

That was my reason for writing here, not to seek resolution (which is clearly outwith the forum's capabilities) but simply to find out if 

a) others are having/have had similar issues recently 

or

b) that they have had NO issue during the course of this week and have successfully processed a credit card transaction on an RM
