Chroma — Air Conditioner not yet installed

I bought one chroma 1 ton AC through Chroma website, it was delivered on 21.04.2023. My order ID is[protected]. Chroma website said same day installation for my city (Kolkata). However, even after repeated follow ups and internal escalations for last 10 days, I don't see any solid response from chroma. Initially different technicians would call me different day to ask my address and then hung up the call, after hearing my flat is in a high rise building. I am really frustrated, i don't have any hope from Chroma team regarding the installation anymore. I understand the free same day installation was a hoax. But i'm very much concerned if they are going to provide any service at all during repair/ maintenance. I think I've made a wrong purchase. There is no actual functional complaint mechanism at chroma again. All my service requests have been abruptly closed without any action. But I will make sure to report the grievance at every forum, so that people can be aware and don't buy AC from this brand. Rather go for the traditional renowned ones, with proper service set up.
