Regarding Credit balance reset

If I remember correctly, I activated Premium using the redemption code on the 22nd of last month, but today when I opened v0, the system prompted that my credit balance was 0. I don’t think I can use up my credit on the day I just reset it.
In addition, I can’t see my credit usage details on the “Billing and Usage” page


never even saw my balance or get to use it , they wont even refund..

v0 is dead
