Cancellation Night mare

I haver been trying to cancel services with Home connectivity for the last 2 days... I have spoken to 4 people, exchanges at least emails, spent over 6 hours... and still not able to!!! Esch person sorts to help and then we do not conclude... some say they will call back and even after an hour they do not. The online option they provide to cancel does not work... is it deliberate... cause if you cross over a month even by an hour you will be charged for the full month... I you ever want to get rid of Home connect ... give your self 2 weeks to allow for the post to pillar game... For the second time this morning...I was promised a callback at 12... that was at 11.40...it is now 12.15... I am going to try and call again... what is gong on with service providers... very insensitive to customers... sadly
