Home Connect Disaster

I've been with HC for nearly 2yrs and the service was good, international speeds were terrible though at about 10% of the total bandwidth. I've canceled with them and served my 1 month notice period but it seems they have not processed their cancelation with frogfoot which means I CAN'T SIGN UP WITH A NEW ISP. I've been mailing their support team who don't seem to care once you aren't a customer anymore, I'm now stuck without an internet connection because of this incompetence. I will be lodging a formal misconduct complaint with the ISPA of this is not sorted out.
