Zencart Gspay intergration

I am having trouble integrating my GSPAY merchant account to my website. The payment module is currently installed and i have followed all the necessary set up steps. How ever i am faced with 2 issues; 1.) the declined test card works fine. The transaction is declined and the customer is redirected to step 2 of the check out confirmation page and is instructed to try again. The approved test card doesn't work correctly. It seems the transaction is approved but the customer is redirected to step 2 of the check out confirmation page and is instructed to try again. Both transactions return response code "2" 2.) I need the item purchased to reflect on the GSPAY gateway. Right now it has the product as "website purchase from (store name)".
