$150 Cash Back Gift Card Per Line Activated with T-Mobile

Hi all,
Took advantage of this offer from REDBOX which is giving me a $150 gift card for each new line I activated (2 new lines and 2 port ins). Spoke to BMP after filling out the rebate form and they said I will receive this cards in the mail 4 months from the date of activation. Seems like this should work for everyone. YMMV
