If you have only played on WPT Global for one month, then you have surely not played enough to overcome variance especially not in MTTs. You won two tournaments, because you got lucky, but then your luck ran out, and now you are losing. This is completely normal and not a "scam". So first of all you need to educate yourself about the mathematical phenomenon known as variance. These free variance calculators are a good place to start:
Poker Tournament Variance Simulator – calculates variance for poker tournaments, MTTs and SNGs.

Poker Variance Calculator for cash games. Displays variance, possible downswings, upswings and probabilities depending on your win rate.

Next step is to make a realistic plan, if you want to become a "for profit" player. And that plan should include largely avoiding MTTs, until you have something like a $500 bankroll. Until then you should play either cash games or SnGs, because these are lower variance formats, and they are also more flexible allowing you to put in more volume.
You can play a few MTTs in the weekend, if you want to, but your main focus should be on the daily grind in either cash games or SnGs. And then you should start with a reasonable deposit like $100 and implement some bankroll management rules. There are many opinions about, exactly which numbers are best, and there is no deeper science to this, but my suggestion for micro and low stakes are:
Cash games: 30 BIs
Single table SnGs: 50 BIs
MTTs: 100 BIs
So for cash games, if the limits are 2NL, 5NL, 10NL and 25NL, then you play the following stakes (or lower):
<$150: 2NL
$150-300 5NL
$300-750 10NL
>$750 25NL
For SnGs if the limits are $1, $2, $5, $10 and $25, then you play the following stakes (or lower):
<$100: $1 games
$100-250: $2 games
$250-500: $5 games
$500-1.250: $10 games
>$1.250: $25 games
Especially with SnGs it is reasonable to mix up limits and jump into some cheaper games rather than wait for the next more expensive one to start. So for instance if you have $275 in your bankroll, its perfectly fine to still play a lot of $2 games, but you are "allowed" to mix in some $5 games as well, if you want to. Once you have $500, you can consider moving to MTTs or at least increase the amount of time, you put into MTTs. Best of luck.
