Aqua Brass

My designer ordered coated brass taps for my ENTIRE custom built washroom last year. We cut the marble backsplash to fit these taps. The wall mounted faucet was also built into our washroom mirror. The finish started coming off onto my hands within the first week. My brass taps started changing colour and rusting, it looked awful by the end of the month. I contacted the store who assisted in the communication process. Aquabrass told me to go buy brasso, I did so and spot cleaned my shower head, it wiped the finish right off (please see picture). I had then refrained and disallowed my toddlers from using that washroom because the finish from the knobs would come off onto my hands and smell rusty and toxic. Aquabrass agreed to replace it. I was told it would take 2 weeks for my parts to come in and the company dissapeared. I had to inquire consistently after not hearing back with any updates. False promises of a 2 weeks arrival time, turned into another 2 weeks, and another two weeks more. Finally when my replacements finally came in 5 months later, half of the items were completely wrong. They sent me a kitchen faucet to replace my bathroom one, the shower knobs were the wrong style. Now I'm in the waiting process again. It's been almost 2 months and I still have not hear back from them. No reply to my emails. I moved into my home almost a year ago and I still have not been able to resolve these issues. I cannot change to another brand because the holes are already drilled into my marble and glass for these fittings. It's embarrassing to have people come over to my house and use the washroom. My brass taps spotted black brown and silver now. So disappointing. (I have attached a picture of the shower bar that I decided not to install because of the condition of us, this is how it looked prior to me even using it; cheap and plastic)
