Nelson Mandela Muncipality complaint

My Dad passed away last year Nov and the muncipal account was in his name. Since then my 75 year old mom has visited the Muncipal department over 10 times with documents ( death certificate, fathers ID etc) to have account transfered to her name. For 2 reasons- to query the over charged electricity and water bills. Invoices and meter readings dont match. The muncipality staff have little to no interest in sorting this matter out but request more documents. Like a permission letter from my late father to authorize her to access the account. Our attorney then drafted a letter but still was not accepted. We have dealt with 4 different consultants with no change. They all seem to hsow little to no interest while the account keeps growing in arrears. There is no compassion for the elderely and it seems that because my mom is a woman they keep giving the run around. Over 10 visits and still no resolution to the high over charged bills or comfort knowing that the account is in her name. Very dissapointing for a woman that lossed her husband unexpectably. She now sits stressing not over her husband passing but ever since stresses about having water and electricty the next day trying to pay this account with a pension income. This is inhumane and so wrong on so many levels. Especially since my mom has personally gone in over 10 times to try speak to someone to have this rectified.
