MBD phishing for client

I don't know if what they do is cold calling or phishing for clients, its second day today that I'm starting to get the irritation from them, MBD claim to have been assigned an my Standard Bank account which by the way I have other attorneys on that account NGR we have made arrangements and I have been do as arranged, I even called both Standard BANK and NGR and from their side nothing changed, standard bank don't have my account with MBD as they claim and NGR says the account is still on their side I advised MBD to contact either one of the parties to sort this out and incompetency takes over and as per them they can't do so. you guys are a ****
