Very bad service

I'm tired of calling and emailing wherelse I'm not getting any response bad service from fedhealth I logged queries since from last year November but no response this January I was told I need to speak to Amanda Prislo the credit controller but she is also not responding to my calls and emails all I get it's a reference numbers with no help

My husband lost his job last year in September due to (covid) where people are losing jobs tried to get in contact with u guys I got no help now I'm getting calls from hospital saying I'm owing them off which medical aid was supposed to pay that amount can someone come back to me urgently so we can sort out the matter coz I'm tired of all this treatment from you guys
