NO COMMUNICATION OR CALLBACKS

3 weeks ago I received an inflated account from this company. I contacted the company and I queried the account. They told me that was that and I could not doing anything about it and I should have my flat checked. I spent the money and got it checked and everything was fine. I sent the email to info metering and Sonja and did not get any feedback. I then called and asked for a portfolio manager of my flats to contact me. I did not receive a call but was sent an email stating that the meter reading was what it was and that I had to make payment. They gave me 7 days to pay not taking into consideration that this account was under investigation. On Friday I had made payment and sent off the email. I emailed Sonja this morning at work not knowing that my lights were already cut asking her to have the portfolio manager contact me. She again told me to contact the call centre. I responded saying that I was waiting for someone to call. I arrived home and tonight to my surprise my lights were cut off regardless of me making full payment 4 days ago. The lady on standby said she was a stand in manager and could not assist me until the morning. No communication in this company between staff
