Incompetence with call staff to get paid account sorted

For some reason my debit order stopped for my contract in July. I saw my account was in arrears and called and was told the debit order had stopped. I asked to have it started again and was told I needed to eft for this month as the debit order would not start until next month. The payment went through. In August again the debit order did not go through. I paid via eft. A few week later I noticed it was still in arrears and called and was told I paid into the wrong account and to send proof of payment and what info was required which I did. Still in arrears. I get a call yesterday and was told I need to specify in the proof of payment that it was paid into the wrong account, I also checked my debit order was back on. I was called again half an hour later and I checked and I needed to send proof of payment with yet another change or it would not be allocated. Sent again. This morning I get a call saying that a debit order for last month and this month was going to go through, effectively I now would pay twice for august. the call then cut out. I tried calling back 3 times and got cut off each time before I even got to speak to anyone. The level of incompetence to get this sorted is ridiculous.
