By doing what the message states: Contact help@tankionline.com and explain your problem in as much detail as possible. In order to confirm that you are indeed the real owner of the account, you'll have to answer a set of security questions, such as when you created your account (rough estimate is enough), what you purchased in the game (in case you did attach the receipts), your IP adress and a couple more. Once that is done, you should be able to get your account unblocked. Kind regards

I agree that jammer is at times an annoying augment to face, however it's not "ruining" drones for everyone. There is also a good number of people that I've seen using Hyperion in battle, which is not affected by the jammer effect at all. That being said, I understand the frustration/annoyance of facing someone using jammer, but as previous replies already picked up it's an augment that you barely face currently and even despite that the Trickster and Defender drone still perform very well. If you don't like your drone effect being taken away, you maybe want to try out Hyperion which works just fine as well in my opinion.
