No service received.

Can we give them a minus rating because a one star is one to many. I have reported my faulty prepaid meter 5 days ago on every available platform. They do not reply at all or even acknowledge receipt. I received one telephonic reference number with a promise of immediate action, because the technicians were "in the area". I follow up every day, but it seems I will have a cold, dark winter. Every second day the telephones are not even working. This is pathetic!
