Chubb one of the worst admin departments ever

We have an account for our Durban branch and have been trying for the last 9 months to sort out our account. First we do not receive invoices for 6 months, then we receive all at once. For the last 2 months no invoices or statements again. Does Chubb not need their payment? I am sure they are the only Company in the Economical climate we are in that does not need their money. We have also been trying to get them to do our Companies name change for the last year, without any success.
