NO CUSTOMER SERVICE AT ALL!!!!

I have an overpriced bill which i have emails to accounts department with reference numbers since May this year, and NOT ONCE have I been contacted to explain the increase or just inform me of the billing process, A company that has such a bad reputation could really do with a good customer service > and then the cheek is that the threatening emails to cut off electricity supply? <br> Being a business person, this does not add up, You treat paying customers like ********* and let ********* get away with free electricity? <br> I am extremely annoyed
