I also had this problem with Them But it is not scamming as you call it, I was trying to get some information about my transaction history which they were refusing to give, I taught it was a matter with them but as i finally found out it was not them at all, It was the bank who would not give them the document I needed and got it after a while whenever they got it of the bank.
I would advice you to be patient,that's the best thing you can ever do to get what you want and that was the only thing helped me out also
