Disgusted with the service

Direct axis - Absolutely disgusted with the service I am getting. Getting told I am in arrears when I'm not. Then after them sending me a message too apologize phone me again to say I'm in arrears. Every time the phone me I explain the whole thing to them and they say sorry we will sort it out but they don't. I went through them for relief plan which they got FNB to loan me the money for April May and June. Fnb didnt pay in April so they were in arrears. They then changed my bank details to let FNB pay that amount for april that was in arrears but now it seems they havn't changed the bank details back as they have not taken the money off as they do like clock work on the 25th. They keep trying to call me on my cell phone but when I pick up nobody speaks and the line is open. I have now been on my phone waiting for 43 minutes with no reply. THIS IS DISGUSTING SERVICE!!!! WHAT DO I DO, WHERE DO I GO FROM HERE.????
