So I have 2 unpaid invoices in Azure portal. Now I've realized that my payment is invalid and I've updated it with new one. Once I've tried to pay past invoices with new payment method I've got "you can't pay this invoice in the portal. Please contact Azure support for assistance". I've created a request several days ago and didn't got any usefull information from MS. Today I've decided to raise additional request on this topic and all of a sudden I can't contact support anymore and seems my subscription has been deleted. Most annoying thing of all is that I can't use portal and I wanted to settle my debt.
If anyone had this kind of EXP, help would mean a lot since microsoft seems unintrested for it.
