Swissquote is a fraud platform that maliciously widened the spread and arbitrarily changes the quota

My friend traded on the Swissquote platform. Originally, he chose to use this platform for the safety and stability of Swissquote. As a result, the Swissquote black heart platform maliciously slipped and widened dozens of spreads on the pound button on April 5, causing my friend More than 100,000 US dollars were sold out. Later, I found the platform and asked why the quotation was different from other platforms. The customer manager Huang Zhicong said that he would appeal to the platform, and said that the quotation of the platform's liquidity provider Bloomberg was not so low at that time. I have provided evidence, but a few days have passed without a clear reply. Maybe the platform does not want to be responsible, so Swissquote is not a safe platform, but a black-hearted platform. I don’t know how to change the quotation at will, expand the spread, and cause losses to customers. Negative value, there is also a problem with the platform's liquidation mechanism. I hope that this matter will be exposed, so that everyone can learn from it. Don't use this black-hearted platform. This platform is not trustworthy.
