Stalkbuylove — no refund received

I had returned certain items and they refunded the the money to their online credit wallet despite the original payment method being a debit card. I requested them to transfer the money back to my bank account. After several requests they debited points from online wallet but they haven’t refunded it back in my bank account. It has been more than a month and no one is responding my mails. Their support numbers are a sham they ask for confidential information like it is no big deal for ex. One of them asked for my card pin. They are ignoring my messages on social sites.
