RocketNet is holding me hostage AND not releasing my fibre line AND collected hardware & router - Still forcing to pay 2 months to them whilst not having service!

At first we were engaging rather well. But when I missed one payment, I reached out to RocketNet to fix my debit order date. After 10 days of non-payment they cancelled my service, which is ok. But upon fixing my debit order date, they double debted me plus reconnection fee. I advised that I cannot pay for a month where I did not use the services and was cut off. DOn't cut off the service if you want to be paid - or better yet - cut the service, but don't ask for full payment! I told them I'd be happy to pay the reconnection fee and the upcoming one month plus pro rata encured. They refused and wanted two full months payments, I then cancelled my service, and they then took the hardware and router from my house, and for the 2nd month now I have not been using their services, because I do not have a router - and they still insist on forcing payment on me. Not only that - they are refusing to release my fibre line, so I'm unable to use any other service until they release my fibre line. Just release my fibre line, and stop holding my hostage.
