I did sign up on 2nd feb and did according to tbe requirements they said but i didn't get
And you signed up in store? Did you get the free SIM anyway?
Do you possibly see the credit and renewal in your payment history? Did you pay close to your plan cost when you renewed? Maybe post a screenshot of it. Blank out personal info.
I signed up during the same promotion and I received credit from it into my account.
It appeared the very next day.
I also activated autopay and received credit for that as well.
And one more credit was applied to my account for being referred by my friend.
All applied credit showed up in my account within a few days of activation.
I hope you get it sorted out.
