Settlement means shutting your account down

I was called from this company handling my Jet account offering me to settle the account giving me a 25% discount, I agreed and promptly made payment, I then asked to be emailed the settlement proof, days later and still no email. I then called again and was told that they would be closing down account because I accepted the option to settle the account which I was not told about, I asked to speak to a manager and am still waiting on that call and then called back to ask for the email which I am also still waiting on, really amazing how these companies can harass you when needing to pay but when all is good on the customer end there is no assistance at all, so typical. I will be going to the Ombudsman if this matter is not resolved in the next 24 hours. I have not given them permission in any form to close my account which to me understanding is completely *******.
