Craig Dunbar is a Star

Craig Dunbar is an asset to this company, what a gentleman, he went far beyond my expectations and delivered the result that looked very difficult 6 months ago when we first found about some underground leakage in our property. Thank you Craig, Castlewater and Affinity water for your amazing services.

Having had a query with my water bill

Having had a query with my water bill, showing the wrong postcode and the wrong address, I spoke to Curtis, who was the only one who I have dealt with on this issue, took the time to sort this problem out. Others who I have contacted in the past said , you will have to pay the bill then try and claim it back!!.

Talking to a human being was good

Talking to a human being was good - by that I don’t mean AI, I mean someone who talks rather than reads from a card - Chris Mulligan was his name, good personality, saw both sides of the situation - smashing bloke.

Bad situation made better with EXCELLENT customer service!

What had the potential to be a very unpleasant call actually turned into an incredible demonstration of outstanding customer service from Jade Bourne. Jade was able to assist in EVERY question I had, gave excellent information and was able to help us get to a point where the issues we're facing are being fully investigated and I'm confident that our issue will reach a suitable solution. Jade's calls should be used as teaching material for what EXCELLENT customer service looks and sounds like.

Tracey Arthur : Saved the Day

Tracey Arthur : Saved the Day!
She was extremely professional, helpful and efficient. Very quickly identified the problem with an extremely high estimated bill. Reassured me that this would be rectified but also warned me that the large amount might be taken out tmrw as it is set up as Direct Debit. I requested a refund on that and was, again, reassured that this would be carried out. I'd give more stars if I could.
Having recently dealt with BT and B3 Comms Customer Service (for the past 6 months!) I just wish they'd both had a Tracey on their teams.
Thanks Tracey :-)
