Faulty payment options

I have been trying to get a hold of anyone at your online call centre that can assist me with an online purchase. I would like to place an order and would like to make payment with a refund card. Every time I punch in my card details I get an error message that says that you are experiencing technical difficulties - it's almost a week later and it has not been resolved. I have explained my dilemma repeatedly to your consultants and they continuously transfer to different departments and/or disconnect my call.

Please get back to me with a solution!
