Flipkart — Smartphone Realme gt Neo 3

I have ordered realme gt Neo 3 on May 4th and got an expected delivery date of May 7th which was then changed to 12th May.
However the product is yet to be shipped even till now (15th May).
Raised an issue and help center said this'll be solved by 12th May.
Tried connecting with customer support manager on 13th of May who only disconnected the call. And after some time customer care said they have escalated the issue to concerned team and assured the issue will be resolved by May 14th 1:00 Pm.
Still no change, no update and the only thing I can do i refresh my page to check if the product has been shipped.
