Boost Mobile Did not honor account promotion of $50 for switching to Boost Mobile. Nationwide

I would like to be counted in that suit if you start one!  Four days ago I saw a promotion online regarding $100 credit for new customers.  I called Boost and spoke to a sales rep.  During the call that lasted at least 10-15 minutes, I asked several questions about the promotion including how to receive the credit.   I Explained that I would be purchasing a phone that day 7/27/14.  The rep told me after I ordered the phone and received it, I should go online and activate the new account and that my account would automatically be credited $100.  So....I ordered the new phone for $500 plus dollars and received it today. I went online to activate the account but did not see anything for the $100 credit. So....I called Boost.  Today I was told that there was no promotion going  on now and that the  $100 promotion ended 6/30/14.  I told them I just spoke to their sales rep on 7/27/14 who in detail told me how to get the promotion. Not only did he NOT tell me the promotion was expired but he explained how to go online and get the credit.  I told them that the credit should be given because I was either lied to directly or the sales rep gave me false information.  It was not my fault and they should honor what the rep told me.  I told them they could pull up  the recordings too prove our conversation.  Of course, I got the same old sad customer service line of "I'm sorry but we can't do anything".  I will join you in a class action suit. After going online, I see I am not the only one who has been taken advantage of by Boost.  Their customer service is set up so that nothing can ever be resolved or no one is responsible.  I thought I would reply to you since you had a similar experience just a couple of months ago.  Thanks for reading. Ps like you, I am a real person based out of suburban Chicago.
