Vox poor service

Vox since i had internet problem from the 9th of March till today, they deducted my money and disconnected my service. i spoke to 13 technicians since they said its in the escalation department till now, its poor service and is frustrating how can 13 people fail to fix the problem. i send e-mail to their CEO nothing happened. i am taking this matter to ombudsman and i want to claim all the cost.
