FNB is ruining my credit profile

On the 10th of March I received a call from FNB, the guy said he was from Chris Hani and Katlehong branch and he was doing a normal check up on the clients with accounts at FNB . The service was good , asked if everything is in order and If I happen to need assistance with anything I must contact the bank

Then Boom all of a sudden I get a “New hard enquiry” that is ran against me by FNB EDG multi product on my clear score credit profile. It suprises me because I didn’t apply for anything at FNB ….. I made means of contacting them , everyone referred me to someone else … to cut the story short, I didn’t get help.

I don’t understand why they would want to jeopardise and ruin my credit profile like that , as a matter of fact I’m moving my business account to a different bank, FNB is full of nonsense!
