REQUEST FOR SIP/VOIP ACTIVATION-NO RESPONSE FOR 6 MOS - Consumer Complaint for Converge ICT Solutions Inc.

I am trying to activate the SIP ALG to allow VOIP calls since we need it for our work. We are not able to reach anyone thru phone, we only get busy tone. We tried sending email request but no one responses, we submitted tickets online but have not heard anything back. We've been trying to reach out to them since May of this year but has not heard anything up to today. Our work is greatly affected and we need it fixed ASAP!Please help
