I use Campbx all the time and have never had any trouble with them.   I do about 4-5 transactions per week for over 5000 dollars and have never had to wait more then 6-7 hrs for it to be processed. I'm sorry some of you have been having trouble but with all the customers they have, it's definitely not a trend for them to be late. I had one issue and sent them a ticket and it was resolved immediately. I just wanted to give my opinion.
