Bring back my electricity units

I had never seen such a service.my meter was replaced on 25 April 2024, I had over 400 units in my meter,and I was promised that my units will be returned, to date nothing has been done,I have sent them numerous emails and I lost count. I am asking myself what people who work there are doing the whole day,if a query takes 2 months to resolve. This proves how useless government sectors are.Thwy are quick to hike electricity prices,and then take our electricity,I am unemployed and I survive on selling food,now I had to take my profits again to buy electricity because this company does not want to return what's due to me.
