They charged me over £1700 for my water bill, found out had a internal leak. Applied for leak allowance but was rejected as it was internal! Now they have sent so many threatening letters and added charges taking the cost to £1900. The people on the call centre were very rude and unhelpful. One of the worse companies to deal with and do not wiish anyone to have to deal with such a unprofessional establishment. I also do not understand why you would get companies to pay for water they havent even used yet by charging 6 months in advance. Just a way to make more money for yourselves without the concern of the effects on SMEs. SHAMEFUL
