Unproffessional Services

I contacted this company requesting a quote the quote was sent and invoice was send and they said we will have to pay before delivery takes place they said it will take up to 2 days for delivery its been 2 weeks now and still waiting at first they respond very quickly in order to get your money then afterwards they do not contact you at all. Do not update you on anything. I am totally disguisted with this service I either would like a refund or delivery of the bricks. Thanking you
