What a horrible experience calling Invesco Hyderabad - Mitarbeiter (anonym) bei Invesco: Mitarbeiterbewertung

The company has a strange policy of not allowing external callers to be connected with someone they wish to speak with!! To add to woes, employees don't respond to mails for days! How does one communicate with people from this company? What is the use of having a board line number in case a policy like this has been instituted.
