Razer huntsman mini keys not responding.

i have the razer huntsman mini for nearly one year now. and it was great for the first 6 months. but the last 6 months it has really been a big pain. First my 7 key was not working, when that got fixed randomly one day. a few days later my f, shift and c key's rgb just stopped working.

This was all manageable but just today my escape, 1, caps, tab and cntrl have stopped working. i have tried getting it out of demo mode as that was a problem once. soon i realized my caps and escape are needed to get it out of demo mode.

i really did not expect this from my keyboard. as there was no accidents with keyboard and all these problems are really just coming out of nowhere.
