Poor Customer service

After struggling with connectivity issues for 8 weeks I decided to cancel my service. A week before my service cancellation went through, the technical issue was resolved. Someone from retention called me and apologized for the delay in resolving the issues I had and offered me a discount should I consider staying. I agreed to stay and she reversed the cancelation request and app**** the discount.

I got billed the full amount and the service was canceled. I have been calling support everyday since 1 may and no one can assist. All they do is escalate the issue and promise someone will call. No one has called. No one replies to emails.
