My card was charged twice by Volacgen Ltd, CP Volacgen ltd (volacgenltd.com) on the same day. I had to dispute it with my bank. Volacgen Ltd, CP Volacgen ltd (volacgenltd.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.
