Extremely unhappy

I have been with Fedhealth a number of years and it has always been great until you need communication. They have no s****s. I have been debit ordered twice this month for absolutely no reason, I spoke to someone on live chat who never got back to me, then proceeded to call the call centre and was told it was a system error, not even a sorry. And then they tell me it will have to be sent to the credit controller and they will look at it when they get a chance. it could take 3 to 4 days for Fedhealth who is at fault, to fix their mistake. R2700 missing from my account due to their incompetence and absolutely no rush to fix it.
