Bad to none communication

I want to leave Home Connect after being a customer for almost 4 years and even in releasing your line they act unprofessionally. I am dealing with them already for three weeks to get my line early released. Then they told me In just had to pay my notice month upfront and they would release my line earlier. That's ok and only fair to me. I paid them already 10 days ago upfront for March services in order to get my line released early. They told me they put in an early release request and now I found out Friday from the FNO that it still is only scheduled for next month. If I pay you upfront for your notice month and tell you beforehand I don't want to use your services for that month amymore, then you should let me go. You got your money, why is it now so hard to let me go to another isp. Unacceptable!
