ccavenue integration problem

Dear service provider, My site is an wordpress site with shopping cart called jigoshop. Along with its default payment gateways,ccavenue has been added as payment option. Although the payment can be made through ccavenue it doesnt give the required inputs to site after completion of transaction. For example it shows "pending order" even if the payment has been successfully made. In an another path the post is not shown as featured even if payment has been made for that. Pleas note that things are fine with other payment gateways and i facing problem only with ccavenue. It is an urgent requirement and would like to request a prompt response from service provider who is comfirtable with payment gateways and wordpress plugins. Best of luck bidding.
