how can i buy i cloud storege

There is seemingly an issue with your current payment method associated with your Apple Account.

You will want to change your payment method, or contact Apple Support.

If you need to change or update your Apple Account payment method - Apple Support

Contact Apple for support and service - Apple Support

i did but it doesn’t work

So to confirm, you tried to change the payment method info and failed, and also then tried to contact Apple Support by phone and failed?

You’ll probably need to try calling again from a different and working phone, then.
