I have the opportunity to start processing with either Allied Wallet or First Date (hi risk merchant) but I would like to know if someone here had previous experiences with any of these companies. All feedback will be greatly appreciated.

Sorry it's high risk merchant

Hey dont have tooo much information but never had a bad experience with allied wallet. First data i never got a response after multiple times of trying to apply so cant say too much...
Question... Fethard anything about them? English user manual maybe?

First Data - this is no brainer. If First Data don't accept you - check Netbilling.com (ask for Mitch or Karen) - they provide high risk merchant accounts and have good records in the industy.
