Test Credit Cards failing in QA Store

Hello, 

I am a developer with the Ontario Dental Association. We are having an issue with any test VISA credit cards failing when attempting to make a payment against our QA Store. 

Please see attached screenshot for info: 

 

ps_store_id = XT54Htore3

This is the message we get: DECLINED * INVALID TRANSACTION=CANNOT PROCESS*INVALID TRANS

Response/ISO Code: 055/40 

Ref no. 660114080016224980
Order id MEMM190411110205000013907360607848

 

I've used multiple test credit card numbers available in your penny value simulator page: https://developer.moneris.com/More/Testing/Penny%20Value%20Simulator

I've used credit card numbers that should always be approved but they seem to decline as well. 

 

Please advise. 

Thank you.
