Flipkart — Customers complaints/queries are not valued

My first purchase from Flipkart and this first impression is very disappointing. Ordered for Realme GT master edition voyager grey on 28th October and the promise delivery date was 2nd November. However order got delayed and they promised to deliver by 5th November which is today but again it seems to get delayed as per the tracker. My phone is yet to reach the final delivery station. Customer care support number does not seem to be available in the app and when requested for call back within 10 mins yet I received call after 1 hour and it was a waste because the lady on the phone seems to least interested and someone who is not serious with her job. I had asked her to escalate the call to the senior as she was not knowledgeable but she then disconnect the line and no further call been received since then. I had tried several times to speak to somebody with regards to my order but then I get a call which the person on the other side chooses to remain silent! No further calls been received so far!! I had even made request to speak to the supervisor in the chat support but then gets denied. Seriously Flipkart is worse than "Club factory"
