WORST SERVICE EVER!!!

WORST SERVICE EVER!!! My father is deceased and had an account/insurance with RCS. I've been trying to get it sorted for the past 2 months. It's like they have the same auto emails on a loop. I've been trying to get things settled but with absolutely no help. I received 1 call and I was told that it will be sorted. I've sent the same documents multiple times and still nothing. They've frozen the account because he is deceased, yet they expect payment!!! What utter BS is that???? DO YOU KNOW THE WOUND THAT YOU KEEP OPENING WITH THE UTTER DISREGARD FOR CX??? I'm at the end of my wits and don't know which way to turn anymore. I guess the next step is the OMBUDSMAN!
