Hi,
Thanks for your reply.
This is more clear after your explanations, it seems they don't know what they were talking about on the phone, both technical and commercial support....
So, from what they said, the plugins paiement which are free were develop by each of them, i mean, VirtueMart develop it, Prestashop develop it, etc... based on the new scellius paiement gateway.
They told me there is nothing develop for Hikashop, and they will send me a cotation for their developers team to do it. They didn't contact Hikashop team about this update of their new gateway paiement? Because they did contact few of them, that's why they already propose it for free.
And if you decide to develop it, i really prefer to pay your team, than their team
Thx again for your help.
