Even though i was incredibly specific about what was required the supplier keeps trying, which is commendable but keeps failing , its not subjective like artwork its a program and i paid extra to have it delivered fast as per his request not mine . I have pointed out where the problem is and he didn’t modify the code to fix the issue. so weeks later no joy!
You can request a refund if he didn’t deliver what he said he would. I’m not sure how long you have to do this after delivery.
