No feedback on my refund for 3 Weeks!

I requested a refund on a deal I purchased 3 weeks back, I received an email requesting the proof of payment, I sent it but I have not received my refund up to this day. I send emails daily, they don't bother to respond because the don't care! BAD BAD SERVICE! I am really disappointed! I want my refund ASAP, it's been too long now!
