Yet again it appears that BT are using the "its not our fault, it's Openreach" get out.
Your contract is with BT ISP and it is up to BT ISP to ensure that the service that they have agreed to provide is done and at the speeds etc that they were contracted to deliver
It does not matter to you that Openreach are the company who maintain the cabinets and infrastructure. You do not have a contract with them. BT ISP does and as already stated your contract is with BT ISP.
It is up to BT ISP to deliver what they are contracted to do. It is up to BT ISP to chase Openreach and have them carry out the work so that BT ISP do not let their customers down. It is BT ISP who are breaching their contract to you and it is BT ISP who your complaint is and if they are not fulfilling their part of the contract, the blame and resolution lies with them.
You need to complain to BT ISP and if need be write to the CEO of BT and let him know how badly Openreach is damaging the reputation of BT ISP and also how poorly you have been treated by Customer Services. I would also advise that you should get the other residents who are affected by this to do the same.
It is about time that all the ISPs including BT put pressure on Openreach to deliver a better service than they are presently doing and not to use the excuse that it is not a BT problem because Openreach maintain the cabinets etc.
I can understand why people post here, just to vent anger and frustration at BT's inability to provide good service when things go wrong. And things do go wrong, too often, in fact every time an "Engineer" turns up at the cabinet across the road.
I'm so annoyed right now I can't tell the latest chapter of my BT / Openreach saga.
I would probably be the last person to vote labour, but I'm actually hoping that Jeremy Corbyn does become PM, so BT can be re-nationalised. Could it be any worse than it is now?
Horse sh*t or cow sh*t...... take your pick.
