Pathetic Service and customer service

The worst service ever, firstly we got disconnected from our lights we had 40 units when we we’re reconnected on the same day the units was 0 they told us that it was our problem we used up our units, then again we put more in and they tell us about a fixed charge in which we had to pay for without any notice of, these people are a complete ******* and I hope someone sues them
