Nimble group blocking my credit

I have not received response from Nible even now 5 days after whiting about them, I have spoken to a consultant from Nedbank the other day and the said that they have also noticed that Nible group has blocked a lot people from being able to apply for credit. My problem is that no one is calling me so i wonder who is Nible? If it is a legitimate company surely someone would have contacted me by now.
