Change in swap (suspected fraud)

I started trading a safe and profitable pairs correlation and swap strategy. The broker increased swap rates without prior notice, without changes in the market and no other broker did the same during the period.The detail is that they called me for a live broadcast on Hantec's social media about my mess, and after that they increased the rates embedded in the swap even more.I still haven't found out if it was something aimed at me and my EA's clients (one would be fraud) or if it was something that affected all clients. Anyway, the new swap rate is absurdly high, for example, the EURHUF pair is more than 7 points negative and only 1 positive, for me.
