How do you report the fact that Croydon Council's website doesn't work when the Council only communicates via its website?

Not content with not emptying my bins the Council now insists I must now report them un-emptied within 48 hours or they're not coming out again... sure that'll keep the missed collection reports down...

... the Council's website is the only way to communicate with the Council which is unfortunate as the Council seems to think I have no bins...

...it says this might be that it thinks this because my address is not in the system correctly...

...and is convinced that my address is somewhere called "FOI Street" - Is this a punishment for having put in an FOI request once?

I cannot change my address on the Council's website and since the only way for plebs to communicate with the Council is via its website I appear to be stuffed.
