My card was charged twice by Bond Rate Compare (bondratecompare.com) on the same day. I had to dispute it with my bank. Bond Rate Compare (bondratecompare.com) then froze my account and said I had a negative balance because of the chargeback. They created the problem and then punished me for it.
Pros: Fast support response|Social trading features|Good mobile app
