Statement request outstanding for more than 2 week

I have asked for a detailed statement more than 2 weeks ago - followed it up numerous time but with no success. On top of this I am now receiving threats that my contract will be stopped if I don't pay within 7 days. The statement needs to be submitted for payment as it was used for a company and is payable by the company. The worst worst service I have ever experienced with any of the network service providers.
