I still can't check out! Been like this for the last 12 hours.

I've been trying 2 days to check out,morning and night. After atleast 4 or 5 mins. of waiting I get this , We're sorry, the link that you clicked on could not be served. We are experiencing a temporary delay due to high volume. Please click reload and try again. We apologize for the inconvenience... I get this every time. I've e-mailed them 3 times,no response. They must not want my money to bad. I tried to tell them a month ago things were messing up but I was ignored.
