Hounded by debt collectors for *****ulent contracts

In May 2022 I found out that 2 *****ulent MTN contracts was taken out on my name. I immediately contacted MTN and made them aware of it. After months of battling with the incompetence, they finally realised. Now, I am being hounded by MBD debt collectors for "my" MTN contracts. Really? Is there anybody working at MTN capable of solving this once and for all ?????
