Improper unhandled Account

I am beyond frustrated and deeply hurt by the way this has been handled. I have an adverse listing on my credit profile due to an unpaid cellphone contract, and I’ve been trying everything I can to resolve it—yet I keep hitting a wall. I set up debit order payments in good faith, only for them to stop without any explanation. I wasn’t notified, warned, or given any support. Since then, I’ve called every number associated with your company, and no one seems to be able to access my account or even point me in the right direction. It’s like my account has vanished, but the negative listing on my credit report is still very real and damaging my financial life. I’ve done my part. I’ve tried to pay. I’ve reached out multiple times. The fact that I’m being penalized, without being given a chance to resolve this, is completely unacceptable. I’m not just a number in a system—I’m a person trying to do the right thing, and I deserve proper support and a resolution. Please escalate this. Immediately. I need someone competent to take ownership of this issue, pull up the account, and allow me to settle it once and for all. This has gone on for far too long.
