Virgin Mobile USA Virgin Mobile promised $70 credit to account won't give it none Internet

 I purchased a Virgin Mobile Chaser for the express purpose of getting a $70 credit on my bill after paying for 1 month of service.  The month that I paid for ended September 26, 2013 and I called to see where my $70 credit was.  They said I did not purchase the phone from their online store. I most certainly did buy it from them and I did the online activation as required. The phone would not work after activation so I called in to see why.  The girl said, turn the phone off for 15 minutes and then turn it back on, that is ALL she did and said.  I did this and the phone began working.

They are still saying I did not buy the phone from them on the online store, so I just sent them the proof of my purchase that I copied from my account with them on their website.  I don't know what is wrong with these people. The purchase was right on my account and they are trying to say I bought the phone from a brick and mortar retailer. I will let you know the next step since I just sent them the proof of purchase from their online store. UGH!
