Endumeni Local Municipality - Electricity

Good morning
At home we have a problem with municipality services, my mom retired in March and went to Endumeni Municipality and informed them that she is no longer employed hoping that they will stop blocking her electricity card but they said she must pay R650 monthly and she payed ends of May and last week when she went to purchase electricity with R100 they took it and did not give her electricity, they said she is owing. As we speak she doesn’t have electricity and she is unemployed and does not receive pension as yet. Can you please help. It’s cold and food is getting stale because it’s been a week without electricity.
