Be very wary of **** and ********** activity

I get called out of the blue from a number *** by Blake & Associates and get told that I have been handed over by FNB for an unpaid FNB Connect account. I have never had a postpaid FNB Connect account, I have never been told by FNB that any of of my accounts are in arrears. I have also never been informed by FNB that any account is being handed over for dept collection, in fact, none of my accounts is in arrears. As far as I am aware FNB have their own internal dept collection process. They have my ID number but my name is incorrect and they are asking all sorts of personal verification questions. I have also not seen any official partnership mentioned between FNB and this so-called Blake & Associates. This place reeks of a **** and ********** activity and would not hand over any of my personal details or money to them, ever! Be very wary of this place.
