I wish that people like that wouldn't throw lingo around without clearly defining meanings of what they are talking about, and where they learned it from. I am sorry that happened to you!
Chakra's can't really be broken. Picture a wheel of light spinning. It's energy. That's a Chakra. It can get off balance spinning. When that happens we can get a blockage of energy.
To get all of your Chakra's back on balance, or even just the 2 you mentioned these are some of the things you can do:
Place a Crystal, like Amethyst between your eyebrows, and if you have a clear quartz point Crystal, hold that in your hand , and then listen to this:

And for the Crown Chakra do it with a Clear Crystal on top of your head, and also hold a clear Crystal point in your hand and listen to this:

Listening to this sounds ( key A for the 3rd eye Chakra, key B for the Crown Chakra),
Placing the corresponding crystals on your Charka's,
and the Clear Point Crystal in your hand amplifies the Crystal's energy.
All of these SUGGESTIONS will all align your Chakra's.
*You don't just have to listen to the singing bowls. You can read through the threads here, and find the Crystals that go along with the Chakra's.
*You can lay down and place each Crystal on that body part, and hold a clear point in your hand, and just lay there and try to be still for as long as you can- 5 minutes to 20 minutes should do it.
*You can listen to soothing music, or a Chakra meditation music.
*You can find what you need to listen to on Youtube.
*You can buy some books on Chakra's.
And please, next time ANYONE says something that is not 100% clear to you, speak up and ask them. It was very unfair to you.
Crystal Matrix is what refers to what the Crystal is made up of. In your case, if you were told to 'build a Crystal Matrix' that is their lingo. I have never heard of that before. I did a web search and found this:

I don't know anything about them.
The same thing with Violet Flame- that could mean several different things. If someone was talking to me about my Violet Flame I would think it would be how brightly my Aura on my 3rd and Crown was. Here is what I found on a web search I did:

Do more web searches on those words, and find something that resonates with you. Share it here so we could learn something too. And don't let anyone take your money if you are walking away without knowing what to do with what they told you.
