Cannot deactiveate my SIM card

I can neither deactivate my SIM card nor
delete my credit card information.
Any help is welcome.

This issue includes deactivation of SIMs:

Update - Just a quick update on the outage with our telephony partner’s APIs. The api to manage SIMs and the data feed are still down and unresponsive. Their teams are working on it, but unfortunately haven’t given us a timeframe as to when it will be back up. We sincerely apologize for the difficulties this causes some of you.

Existing Particle SIMs are still able to connect to the towers and the Particle cloud, this still only affects managing SIMs, seeing data usage and notification and pausing based on data caps.
