Double debit order and payment but no refund

Good day. On the 16th July my services were disconnected for non-payment. To restore my lines I made the payment of R1200 and attempted to have the service re-connected. The 808 service was interrupted and the call centre was closed. I then went to check my account and I actually had made the payment which they said I didn't make so now my account had been paid for twice in July. I sent the 2 x proof of payment via email as the call centre was still closed. Eventually I got an email back saying my service had been reconnected and that the debit order for July would not come off and my next payment will only be in August. Well surprise surprise, another R1000 came off my account on the 15th July, now, on a tight budget I am that amount of money short for the month. When I try and mail all I get is your account is up to date and your service is reconnected. But I have an email in black and white stating they are at fault. AM SO FRUSTRATED AND BROKE!!!!
