Never answer MBD calls, wait for writing.

Never take a call from MBD for your peace of mind. The moment a consultant says they are from MBD, put the phone down and wait for your day in a court of law so that you can expose their lack of customer service before a reputable court of law. They threatens clients and they are so rude. They always put the phone down on your ear when you reason with them. So do the same thing to them, just put the phone down. They must engage with you in writing because they lack phone etiquette.
