I am the treasurer of a small amateur theatre in Surrey. We have owned the theatre for over 30 years and our water is supplied by SES Water. In February we received, out of the blue, a letter from Castle Water claiming we owed them £2600+ for unpaid invoices going back two years. We had never seen any of the invoices and when we did see them it was obvious it was nothing to do with us. CW continued to send invoices, and threatening letters, over the next few months. I enlisted the help of SES Water and eventually, in November, CW conceded that we owed them nothing. There was no apology, and so I have written to their CEO suggesting a payment to the theatre by way of compensation for my wasted hours.
