This must be the most incompetent company I have ever come across in the past 40 years! They send multiple invoices with varying amounts which do not correspond with each other. They have no idea what they are doing. Their estimate for December was 200 (yes....200) times what I have used in the past 6 months!! It is unbelievable how poor they are. Only go with them if you like ringing call centres every day to listen to mind numbing music and then explaining your position multiple times to multiple people and yet still get nowhere. I am not sure that they could be any worse. It is a full time job just dealing with them.
