Nokia — Mobile not recd

I handover blue color mobile but they replaced with black color without my knowledge . Secondly i checked that mobile also, fully charged and i switched off mobile. Later i tried to switch on the mobile same problem, not at all switch on. I don't know what kind of service their your doing. Really fedup. I purchased on 14.11.2021, still i didnt get my mobile. Not even single day use it. I told them to collect the black mobile and refund my money but they replied like this"In response to your concern regarding Nokia 110, we would like to inform you that there is no refund policy there is only 12 months replacement warranty for feature phone device and 6 months warranty for accessories if it meets all the warranty guidelines, that is there should not be any physical, cosmetic and liquid damage in device and Further, we would like to inform you that the replacement is depend on stock availably so we will not commit for the device color." i paid for blue panel device, not even single day used it. How can they say based on availability stock they have replaced with black panel device it seems. If i check third party portal still blue panel device stock is there, how can they blame me. I have sent more 30 mails for the solution, nothing happen. Meanwhile if they replaced with new mobile how that's mobile also facing same issue. Might be other person brought black panel, would have same problem, those stock returns to me by the name shake of replacement. I requested you to kindly look into this...
