FNB Customer care call centre Not Responding to Customers Timly

I am an FNB Customer who had a ***** debit order from Luvmore for R95 on 25 April, 2018.I was able to reverse it as it is less than R200 but I have been endlessly contacting FNB Customer care number since April 25 to find out more details on who these Luvmore people are and to STOP them from ever again debiting my account *****ently but FNB customer care call centre agents are not answering calls.I am having to wait 6-8 minutes with no answer.This is really unacceptable service.
