What is the Magenta Max switch $200/line promo code?

Ok so I ended up getting my rebates. I was told over and over again that I would be able to use the rebates anywhere of my choosing. However when I received the three $200 cards I was not able to use them anywhere at all. I tried to purchase a better unlocked phone through Amazon, it didn't work. I tried using them in a T-Mobile store, one T-Mobile store said that they do not except those Virtual T-Mobile prepaid cards at all, the other T-Mobile store couldn't figure out how to do those kinds of transactions. So ultimately the only way I was able to use the $600 in rebates was to put it all on my bill account. It's pathetic that they lie to potential customers like that. It's definitely bait for potential customers to switch them when you do switch you're screwed. They think that you'll just roll over and take their abuse. Well T-Mobile. I'm going to keep their service as I have my home Internet and cell plan through them now but I'm not buying physical phones through them, I'll order those from Amazon and pay in full. Because looking at these T-Mobile leases for these three phones I'm paying $125 over retail for each one. T-Mobile lies their about everything. I do not recommend T-Mobile to anyone.
