Our company received out of the blue…

Our company received out of the blue several invoices for our waste water that we had no knowledge of. SES water had sold that part of our service to Castle Water without our knowledge, who then opened an account without our permission. I tried several times to contact customer services via phone (no one answered) and via chat which then timed me out on several occasions. I finally raised a complaint and Sarah Byers, a customer service agent responded. I found her to be very helpful and efficient and we have finally resolved our issue. Castle Water need more employees like Sarah.

Aged query not resolved

Having had this site in query for 2 months, I have finally made headway with the assistance of Castle Water employee Christopher Milligan. He looked into the query in depth to try to give me the most up to date information, and advise the correct way to take this query forward. Thanks Chris, you deserve a Blue Peter Badge :)

I spoke to William at Castle Water this…

I spoke to William at Castle Water this morning, and I wanted to say what an outstanding experience it was.

From the moment he answered the phone, William was friendly, cheerful, patient, and genuinely helpful. I had been very concerned about a large bill, but he took the time to explain everything clearly and concisely, answered all of my questions, and put the necessary actions in place to resolve my issue.

What really stood out was how reassuring and organised he was. He reminded me to make a note of all the reference numbers and ensured I understood exactly what would happen next. By the end of the call, I felt completely at ease and confident that everything was being dealt with properly.

Excellent customer service is becoming increasingly rare, and William is a real credit to Castle Water. Thank you for turning what had been a stressful situation into such a positive experience. I truly appreciate your professionalism, kindness, and dedication.
