Enrollment to the Program from El Salvador

Good day to you all. I have been trying to enroll to the Program using a salvadoran phone number, as individual Developer, and using my Apple Account (former Apple ID). During the past three weeks I have received the You Cannot Be Enrolled at this time; I repeated the process during the first two weeks, then I let it rest for some days and tried again this week with the same result. Also, I opened Support Cases but this far, I cannot enroll. I will appreciate your recommendations.
