Query regarding invoice

I had been receiving a lot of emails regarding an outstanding amount we owed on our account. After explaining the situation to Leanne Sinclair she sorted the issue out immediately. She was very helpful and understanding of our situation.

Disappointed private person

Disappointed received a mail your case is closed then had a fine of £105.00 because I owed £40.00.
No effort was made to e mail me a letter to say there is a last bill and if they did sent it to my old address where I lived previously.

Dispute outstanding balance due to additional charges being levied

Customer Service support from Jamie was fine but it seems that nobody has authority to review charges levied to the account whilst the sum owed is in dispute.
No emails received confirming bills but Castle are adamant that because there records show an email address, it must have been sent

Absolutely terrible experience.

Absolutely terrible experience.

We recently moved premises and were given a new account. Unfortunately, the new account was automatically set to paperless billing, and we were never aware of this or received any invoices.

A few months later, we were shocked to discover that the account had already been passed to a debt collection agency. Instead of being given the opportunity to pay the outstanding bill, we were suddenly facing a bill of nearly £900, including over £600 in debt collection fees.

I contacted customer service to explain that we had never received any invoices. Rather than trying to help, the representative was extremely rude and simply told me that if I didn't pay, they would disconnect our water supply.

We have always been willing to pay our genuine water charges, but it's incredibly unfair to send an account straight to debt collection when the customer was never aware of the invoices in the first place.

This has been one of the worst customer service experiences I've had. I sincerely hope the company reviews its billing and communication process so other customers don't end up in the same situation.

Michelle Sek was very helpful

Michelle Sek was very helpful. I'm moving my business and wasn't sure if I needed to keep the direct debit going and she very quickly advised that I should expect a final bill and it will be collected using the direct debit after which I can then cancel.
