How many times do I have to ask for my money back.

I finally got a response from Asheeqah Sampson indicating that they will do a refund as the supplier cannot replaced the damaged goods. I sent my bank details, proof of the payments to Groupon customer support and only got one of the 3 refunds back. What in flippen heaven's name am I to do to get the remaining R878.00 (R439.00 x 2) refunded back to me. It took 5 seconds to debit my account with the money and 2 months for a refund. C'mon lets start providing some customer service here or provide me with a contact number for your useless customer service division so I can tell Asheeqah Sampson exactly what I think of her pathetic service. or kindly get her to show some customer service and contact me on ***.
