Reliance Digital — Haven't received the products even after multiple delays

I purchased a mobile phone via reliance digital website on 23rd Jan 2023(Monday), estimated time of delivery while making payment was 27th Jan 2023(Friday). On 27th I received an SMS following an email informing me that I will get my phone on 30th Jan 2023(Monday). After that I call Reliance Digital Customer Care: [protected], they assured me that they have raised the complaint and will try to resolve the issue asap.
Still waiting for my phone.
