I have a client who decided to leave Mercury and move their CC processing to Elavon. I have had nothing but issues. Their tear sheet didn't have any of the gateway URL info and it took me a week to get out of them what to use. Now I have an issue where credit works but debit does not. I get an error back of "Unknown Issuer". The processor has the same error on their end. I spent about 2 hours on the phone with their processor tech support to be told that I have to enter multiple Sharing Groups in the EDC settings to make it work. Of course you can only enter the one. Has anyone ran into this processor or know what might be going on. According to the sales person they work with RMS all the time but my gut tells me they don't as the tech support knew nothing about the program. I have verified all the settings they provided and everything is correct on my end.
Thanks
BP
