Pathetic support and billing from Sage Payroll

I was told by Sage Accounts and Sales departments that the "outstanding invoice" emails we received were to be ignored because we do not owe anything as we had paid for the 12month package.

We now find ourselves in a situation where our account is blocked and we are not able to do anything. We needed to access our account urgently otherwise we can lose our employees. I spent about 2hrs on the phone calling different support numbers that just kept me on hold when transferring to the Accounts department.

This is a huge business risk for us as we might lose revenue, can someone assist urgently to unblock our account as we dont owe a single cent, but instead we've paid for 12months in advance for pathetic service!
