Terrible service

Our prepaid electricity is giving us problems, we have called the department to query this and have been promised that someone will come to our place and assist at 5pm as this is the time we normally get back from work, nobody has come through to assist, we have contacted the call center with our reference number given by them, and have been advised that someone will attend to us once someone is available, I mean is this how they operate or is it because they are not doing their jobs, the query was logged the night before and now we have to beg for assistance, our food in the fridge is getting spoiled yet they have time for silly games, if they are short staffed and know that they have places to be and people to assist then something must be done about that, we have not had electricity for three days now, instead we are being told that only when someone is available, will they come and assist us, as if this is new to them, why are we still voting?
