Can anybody help me understand why I have to keep credit balance positive when I am on pay-as-you-go plan ?
I moved to pay-as-you-go plan several months ago, each month I pay a bill based on last month usage, it charges automatically my credit card linked to the account. My usage is always below monthly budget and within limits assigned to my tier. Suddenly today my account was blocked with ‘code’: ‘insufficient_quota’ (-1.29$). To unblock account I had to recharge balance. Everything is working now, anyhow this practice of forcing users to keep credit balance positive despite being pay-as-you-go user is not clear to me.
