I would like to first start by saying I Purchased a Fontana Shower set on Amazon in 2014 the shower started becoming cold and I was told by my plumber I needed a thermostatic cartridge when I contacted horzon direct depot Who sold me the shower set they were unable to find this cartridge I was getting ready to go on Amazon and tell people not to buy this Fontana shower set at $700 when I decided to contact Fontana. I would like to say in an era where customer service has become increasingly obsolete Marzena was amazing she was incredibly knowledgeable and attentive to my messages I could tell she was working hard to find the part that I needed instead of writing a bad review on Fontana and telling people not to buy their shower sets instead and I am now thoroughly impressed and would recommend them to anybody she is a great employee for your company and should be rewarded or promoted and I hope you do so thank you very much!
