SMART METER ACCOUNT A COMPLETE MESS!!!

We moved into our new house during April 2015. I was informed by the previous owner to contact Smart Meters, which I did. I was informed by the call centre agent that I can register on the account of the previous owner ***), which I also did. I have made payments totalling R4 355,38 up to date. On 23 November, when I got home, my electricity was cut off. I called the call centre, who then advised that another account ***) is in arrears of R8000! This account was not yet registered in my name, and it was the first time that I heard of this account number. I then had to register the account in order to get my power back on, which I did. Smart Meter is only prepared to give credit of R3300 of the payments which were made to the old account. The next day, I get a notification to say that if I don't pay the R8000, they will cut my power off. The call centre advised that I need to pay the difference between the amounts (being about R4500). One day later, as I have not yet been able to pay such a huge amount yet, my power is cut off again!! How is this reasonable to expect someone to pay R4500 of which they were only advised 2 days ago, within such a short timeframe!?!?
