cached Small adjustments may be needed
Every three months, our system automatically reviews your payments against your usage, just to make sure you're not paying too little or too much. If we need to make an adjustment, we'll let you know.
Sometimes, you'll have used less than you paid for, so your account will show a credit. If you've used more than you paid for, your account will show a debt.
But we work it out. We'll tweak your payment amounts and you'll be back on track.
