We bought a shower mixer on their website the information provided said it came with a ten year warranty after 10 months the thermostatic cartridge failed, it was replaced with no problem, they sent the correct cartridge everything fine, two years later the cartridge has failed again contacted them they sent out two replacement cartridges, they were the wrong cartridges, contacted them again the shower was no longer and they would have to source parts an email arrived informing me that they would have to strip a valve down and send the cartridge within seven to ten days the next day another cartridge arrived again wrong one, tried to contact them by phone as I had done in the past, however as of yet I have not been able to get through so I decided to use their live chat the operator refused to accept that I had an account after taking my details after a series of questions I provided them with an order number. Finally they agreed that that I had bought something from them I explained that I had been sent three cartridge's all of the being the wrong, they then started argue with me that the shower did not have a ten year warranty yet the paperwork said it did, their website said it did, the three people I had contact with said it did she wanted proof that I had a ten year warranty. I said to her that all I wanted know was if the cartridge that arrived was the one that they were to take from another valve if it was it was the wrong, she confirmed it was not the valve I am currently waiting for she was adamant that the shower I bought did not have a ten year warranty It was very hard to get answers to questions while they dominated the chat with issues about the warranty. up until I came into contact with this individual I had had very good service at this moment in time I'm not confident that I will receive a new cartridge and have resigned my self to the fact that I will have get a new shower valve this of course creates a whole new problem as it is concealed in the wall
