Insufficient information provided.,.unwillingness to engage

I keep on getting calls about an account with FNB. I have NEVER opened an account with FNB. Despite stating this...B and L refuses to provide proof of any account that I have. Nothing is sent on Email...no statement...no details. I cannot pay an account I do NOT have to a law company...that sounds like a ****. I called B and L call centre and requested this info. Despite this...they continue calling me with the same info - which is no information and asking the same things and not providing any proof. I will happily pay an account I have ....unfortunately their is no interest in providing any details regarding this to me...Their website is dowbn so I cannot email them either. I will log a complaint with the national credit regulator and CDC in an effort to get Brooks and Luyt to engage on this matter.
