The most useless, incompetent, and unprofessional company that we have ever had to, unfortunately, have to deal with. We have a wrongly invoiced and billed for over 11k in JANUARY. The actually used amount was more 200-300 GBP. We have spoken to almost every single customer service advisor (Mark K, Sam K, Lynne C, Kat C, Sam S, Mohammed, Hassen K......) and to date even though they have admitted they have made an error and falsely charging us for 3000 units of water WE DID NOT USE, we have received yet another threatening letter of further action and penalties THIS MORNING! This is mentally tormenting creating unnecessary distress and harassment. One star is one star too many !!
