disrespectful, lazy and *********** consultants at TFG CUSTOMER SERVICE!!!

Called customer service to change my contact details and I was told I should visit the store otherwise if done telephonically my account will be blocked I opted to be assisted telephonically as I'm certain with the security questions they were going to ask me, I'm told to hold for the next available consultant, as I get transferred I hold for a long time just so I get to the next consultant before I could even say hi I'm told my line is bad and the lady just hung up....bad customer service it is no way to treat a customer TFG CALL CENTRE should take their consultants for customer service training I'm embarrassed on its behalf such behavior will cost you customers.
