Bad service

I currently have funeral cover with Hollard. Making changes is a mission. I've called in over 2 months ago to add & remove people from my policy. I called in again this week to make changes. I've emailed complaints, still no luck. After being assured of one person being removed from my policy, I've still been debited this morning. The 2 new people I've added, I've still not been debited for. When I checked my policies online, there aren't any banking details added. I tried updated it online, but I received an error. Nobody has contacted me what so ever. This is truly unacceptable. As I'm a paying customer, receiving bad service. Investing my funds in a bad company such as Hollard!!
