Hyperli cancelation and refund

Kindly assist me here. I bought 2 spa vouchers on the 20th of October through payflex. I cancelled within the 7 day period so I can get my refund. I sent a lot of emails only got 1 response which did not make a difference. The vouchers don't even reflect on my hyperli account. Now the payflex installment bounced because hyperli did not inform them of the cancelation. Can hyperli just refund me back my money and inform payflex of the cancelation. They are basically de*****ing us here!
