To cancel the service .

Hello, my name is Prem Chhantyal .This message is about service cancellation. The reason to cancel the service is because i have moved to another place so i don't need it. I have been to Torres Vedra Nos stores many times to cancel my service. However, they asked me to call the call center. I tried to contact the call center many times, but I could not reach. Since July I am not using WiFi but i am still getting bills form N.O.S. What should i do. Please help me to fix these issues, I just want to cancel the service. Looking forward to hearing back from you.

Thank you,

Regards,

Prem
