Cycle of Madness do not deal with Home Connect

I have been with Home Connect for two years and they have never been able to supply the support or service as contractual promised. I f you phone they expect you to be the technician and the solution inevitably is to switch you from one line to another (which works for a hour or two). I upgraded my line thinking that a unshaped/uncapped 100mbs up and down would work. No such luck, they can not supply even 40% of that consistently. Various calls and emails have produced nothing, asking for escalation has resulted in nothing, just some new person every time trying to start from scratch and following the generic narrative. I canceled asking for immediate release of my line but paying for the whole month, since then I have spoken to various staff who "understand" and will "escalate" to release my line and prevent them from charging an additional month for services NOT rendered. All this only to get emails a day or two later stating that they will charge an additional month, nothing related to my line or my complaint. So I phone again to speak to a senior manager (who does not have a contact method and will be asked to phone you) only to have the whole cycle happen again and no escalation.
