Extremely bad customer service.

Never have I been soo much dissapointment with a company's customer service. I placed an order and the money was taken off of my account but the order cancelled due to "non payment". For a full 4days I have emailed, sent a msg through the chat service, their phone line is forever "experiencing high call volumes" and cutting off calls.In this 4 days no one has actually gotten back to me. I have emailed them before when struggling to make payments and the response was almost immediate. And this is money, my hard earned money that we are talking about. But I guess they don't care much for their customers
