Hi team,

I have purchased two phones from amazon i. E. "moto g4 plus 32 black & moto g4 plus 32 white" in which i got offer of 45gb free internet on vodafone connection.
The issue is that i got offer only in one sim which was inserted in white color phone but in second vodafone sim which was inserted in black i got only message that "congratulation you are eligible for free 45gb internet" but its not added in my plan or not activated.
I contacted to vodafone several time always they says that wait for 48 hours it will get activated but still it is not activated or added, now vodafone is refusing and giving various diffrent diffrent reason.
Please help me asap
