I'm positive that I have been shortchanged units from last month. I can't get any joy from e-mails - think their inboxes are full - and they won't let you post on Twitter. Consequently other people would also receive less units than they've paid for. If you have any helpful advice on who to contact it would be appreciated. Or even better if you are connected to JHB City power let me know how I can get this resolved. Thanks.
