Flipkart — Mobile phone ordered during sale is not getting delivered

I made a order of one mobile phone on 15th of january 2023. Promosed delivery date was 16th but unfortunately even after coming to my nearest hub it didnt got delivered. From that day i am following up with customer care but no resolution. Customer care told me that it got misroute and i have to put a fresh order and i did the same. So i placed one more fresh order on 20th january and the promised date was 21st january. This time also the same unforutnate event happened with me and the product again breached the delivery date and got misroute. Every day customer care is asking me to wait till 7pm and making false promises.
