I was sorry for your loss, however before giving a bad review and talk about Traderswas as they stole your money, please take one more look at your chart and read also their email more carefully.
As far as I see your chart it shows that the price was about 1 pip from the SL when it got trigerred and then prices changed direction.
Reading TW email they also mention the “Ask price”. Can you please also check your MT4 and tell es what price does your chart show? If it is not the Ask price then there is nothing to talk about.
I personally do not trade with them but often there is drama here on the traders side although the broker did nothing wrong. So lets observe it first in detail.
