Traded one position without stop loss by trade copier and have got huge lost

Hi,

I had recently suffered by huge lost due to a signal provider name Instantpip.com had traded one position GBP/USD without put stop loss in my MT4 account by trade copier. They have clearly mentioned on their website that they always trade with stop loss and take profit. See below their quote :

'The trades are executed lightning-fast and accurately, always including Stoploss and Take profit, thus your capital is never at risk while you can enjoy outstanding automated yields. This is how Instant Pip can help you fulfill your dreams of living a more complete life'

I lost my capital due to their blinded and over confidence attitude. I have made many complaint but they are not ready to give back my lost only offered me two months free subscription. Now I don't have a money to trade due not working because of long term illness about four years and having huge financial problems.
I want my lost money back because it was a fault from instantpip.com side.
Please reply and guide me.
Many thanks.
