The worst company I have had dealings with. Ever!!!!!!!
I am being forced to rate them as 1 star. They are a zero star organisation.
On 27.12.10 we have been left with no water supply for over five /six hours and it took 45 minutes to get the Customer service of TW to talk to me. I wish we had a different supplier. TW is a truely Zero rated company.
I couldn’t agree more D Clarke. Unprofessional staff, arrogant operators and inflexible policies are the least examples I can bring up here. To install a water meter I was given eight numbers to call to make an appointment. After ten days calling all those numbers over hundred times I called the main office for help. The answer was: sorry we cant help. Isn’t that pathetic ? Thames Water, a big name, don’t get trapped.
Without a shadow of doubt this is worst and most incompetent bunch of humans I have ever had the displeasure in dealing with. I built a new house and have had to deal with all the services and by a long long way thames water were the worst, first they rip you off then they sub out the work and then declare no responsibility, they cannot even get the correct billing address after ripping me off to the tone of nearly 3k absolutely shocking and dismal service. I agree they should be shut down. The main issue is that they have no competition and they know this, so they are arrogant and have no regard for the customer. If this was any other business they would be bankrupt.
I give Thames water a o rate, but can’t cause website want 1 star plus. Had billing problems with them last year, guess what their fault. Got a debt recovery letter from them-guess what their fault & no apology. Now i being charged double costs this year for my water and nothing has changed. Try to phone them impossible kept waiting 20mins then i have to put phone down. BAD CUSTOMER SERVICES
Well, there’s nothing that I can say here that’s not already been said. Thames Water is a really terrible company, and it just aggravates me that such a bad company is the most successful in the UK…
For any problems you may be having with Thames Water, may I suggest sending a complaint to OFWAT? (regulators) they will go down on Thames Water like a ton of bricks, believe me
I hate Thames Water. They have been sending final demand notices for me when they haven’t send the water bill in the first place. I wish I could switch supplier. I do not even want to give 1 star for this company.
Just spoke to a bloke called Colin, he was very polite, efficient and dealt with my problem really well. The Thames Water website should state more clearly that the phones ARE answered after office hours; I called at 10pm even though the info said closed after 7pm. I nearly didn’t call at all due to that… All in all, very good.
Just had my water bill in for next year for family of 4 (2x kids 2x adults) I think £612.00 is too high but nothing I can do. Monthly payments have now gone from £40.00 per month to £51.00. Just what I need when my hubby has lost his job.
