Poor Service and no communication

As an existing customer, I anticipated that extending my cover would be simple and easy. It has now been 4 months and I still have not received any communication or commitment to a quotation that was presented to me. Time was spent arraigning meetings, answering questions and following up with documentation to finally accept a debit order with everything in place only to find out the debit order or policy was never filed. I have written multiple emails following up with multiple people and get no response what so ever. God forbid my family has to deal with such poor service when I die.

Does anyone have a recommendation for a trusted and a prompt service provided who can do my will?
