Oziva — Order rejected money deducted.

I placed one order in oziva 49/- it is cancelled on 14th.next I placed another order 948/-. It is also rejected. But they didn't send my money back to me. I have everything evidence of that transaction so that easily teach them a lesson. I mailed them, and contacted through Instagram but no ise they didn't reply. They don't know how to treat customer. They know how to influence people with cheap publicity. Please teach them a lesson I needed my money back. It's 7days already my money doesn't back. Please help me sir...
