Openweb fails to respond to cancellation

I cancelled my contract with Openweb due to putrid or non-existent service on 28 July after months of complaints and intermittent internet broadband service. Since I sent the cancellation email there was no confirmation or any communication from them until 12 August asking for further details.<br> This is frustrating to say the least. It smells of deliberate delay for financial gain.<br> I would not recommend them to anyone. My experience has been the worst of all service providers I have used
