Bad service need refund and plan cancelled can't get assistance

Hi

I need urgent assistance I keep emailing and get told that I will be contacted in 2 to 3 day and nothing happens I have been emailing since the 28th of June. I did not receive the details and then later emailed to cancel since I was not getting feedback. I have also called a few time. I see a debit order has gone off I need a refund and for the subscription to be cancelled I have not received anything and do not want it as this service has been so bad. When I called again today I got told the same thing 2-3 days asked to talk to a manager but did not get put through. I was told it's been esculated. Once again it is not the afternoon and have Herd nothing once again. I have no idea what to do I just want it to be over. Can someone please help me. Your IG reference is: plan179638
