Website failure

I'm attempting to change my payment type from PayPal to another method. I couldn't see any way to do this so I attempted to access firstly your help centre and then secondly your contact centre ... on both occasions what I presume was "Cloudflare" kicked in and locked me out from both sections of the site. Screenshot attached so two requests please ... firstly please advise how I can change my payment type and secondly ... please, please sort out Cloudflare. Thanks.  

Hi Periander! Since you are unable to connect, I'll see if I can get any attention on this for you.

Cheers

UPDATE Found out how to change my payment type, in the end it was really quite simple, I'm still a little grumpy about Cloudflare (it seems to hate me/my IP) but there's no urgent issue anymore.
