Poor and unprofessional service

I received correspondence from Liberty Life and it had incorrect information which was confirmed by their Call Centre agent who then referred it to their Actuarial department for advice and will get back to me. It has been over a week and no has come back to me with any news. Furthermore , previous correspondence from Liberty Life contained their Financial Advisor contact details and when i tried to contact him, I'm told he had left some 6 months ago. For a so called big company it is unacceptable and unprofessional, no wonder the share price is depressed.
