still no service - paying every month

I have been with Autopage about 10 years now, never had any issues until this year. I have had managers promise to call me back, ive had people put the phone down in my ear from the call centre. Ive had call centre agents who keep putting down the call when i call. Autopage sort out my account. this is the last time resort. If this is not sorted out by the end of this week I am going to take this to the newspapers, I have proof in black and white that there was a mistake on my account and you are just ignoring it. You have breached your contract with me. I have never skipped a payment yet my account is still not right and i have been cut off.
