SIR — Can someone in Umeme explain what is going on with their billing system? I pay my bills on time but every new bill has a higher figure than the one before, despite the fact that I haven’t installed any new electrical appliances in my residence.

I am using Umeme only for lighting (with energy-savers), cooling (fridge) and ironing. They should explain what is happening.
