Terrible customer service

I have been a loyal customer with Wirulink for going on 6 years. I am now moving home and unfortunately can no longer continue with my contract. I ask them to please send me a penalty quote for having to cancel early - they "graciously" offered me a penalty payment calculations....the FULL contract Value. I am not going to be using the service.... I am willing to pay for the hardware, so that is covered.... A penalty for admin and contract fees yes. But trying to deal with the accounts staff is like talking to robots - they are unable to explain exactly why they doing what they doing. I never skipped even one payment - but feel like I am being kicked in the teeth now. Definitely stopping to recommend them to friends and family
