There is NO start date for this promotion and it just says that the offer ends 12/31/14, meaning it's an ongoing promotion at this moment which ends on 12/31/2014.
I did a port out from MetroPCS(one of selected carrier to be eligible for this promotion) to Cricket Wireless on 2nd of November 2014. So technically, i am eligible for the promotion to get a $100 account credit because I meet all their criteria of doing the port in to Cricket wireless from MetroPCS before 12/31/2014.

In that case, i should have received a $100 account credit 5 days before the end of first month's service period, but i did NOT get.
When i called their customer care, they are saying i did not qualify for this promotion by telling me some start date by when my port in should have made, but their website does NOT tell anything about the start date.

Now i am feeling like i am being cheated and harassed and wasted my time. I have captured the screenshots from their website about this promotion which i am going to upload here.

If i don't get my $100 account credit, i am gonna pull them to the court and take a drastic legal action against them in the case of fraud, cheating and harassment and worst customer treatment from their customer care.

I just need a full compensation on this.
