Unprofessional conduct and lack of response

I have a case of ID *****, in that an individual had opened an account with Neotel (using my ID **********ly). I have repeatedly requested proof that I signed a contract with Neotel and have provided an affadavit, etc. confirming that I have never opened an account with Neotel. To date, I have never received the requested documents and have had no progress from Neotel (in terms of investigating the ***** and closing the account against my name). Neotel has subsequently handed over the account to MBD credit solutions, which has proveeded to threaten legal action - still, to date, the required proof has never been provided and the ***** has not been investigated. This is totally unprofessional and, needless to say, I will never become a customer of Neotel and neither will anyone I know.
