No invoice, but expect payment

I've not received an invoice for six months from them. Found out today my line was suspended, and the outstanding fees are accumulating interest. I'd love to pay you if you'd send me an invoice like any other company rendering a service.

On trying to figure out what I owe, I found three different amounts on their site?

Now I'm assuming I'll have to wait a few days before line is activated again.

I'm tired of this 'service'.
