Thinking it’s ‘fishy’ that this problem arose at the same time you decided to leave is a little paranoid, in what way would BT benefit ? , if anything, if it were possible ( and it’s not ) the losing provider would make your final days better , not worse , that way your new provider would seem poor in comparison , and you more likely to regret moving , irrespective though , there is no way for BT to do what you are suggesting , and as far as Openreach, it doesn’t matter to them if you are a BT customer on an Openreach line or a customer of any other ISP , it makes no difference to them .
As far as your your misunderstanding of the switching process, that’s understandable, why would you know , however , you would think your new ISP should know and would have offered you guidance, presumably they didn’t , but you picked them , so ultimately you live by your decision, you asked for BT to cancel your service, that’s a 30 day notice, and that’s what was set in place ,
You have every expectation that the service should work during the 30 day notice , BT have apparently let Openreach know that the original ‘fix’ didn’t work and so OR are going to revisit, in the circumstances what more do you expect BT to do ?
As far as your final bill , if you have a reported outage that is stopping your service working completely , then BT as a member of Ofcom automatic compensation scheme , BT guarantee you will receive a payment ( a reduction on the final bill no doubt ) , for the lost service time , is your new provider part of the automatic compensation scheme ? , not all are, obviously the cheaper end of the market can make savings in ways not necessarily obvious, like backhaul capacity, like automatic compensation, like the service level agreement ( SLA) they have with Openreach as far as repairs are concerned , different levels of SLA , different pricing , BT take the highest and therefore most expensive SLA , what about your new ISP ?
