I rang BP Pulse and was told in no uncertain terms there is nothing we can do. I explained politely that my charger was within its 3 year warranty and they should replace it. The gentleman said we don’t do chargers any more and have nothing to replace it with.
So I telephoned Motability and had a chat with a very lovely lady. Explaining the problem. They said they needed to talk to bp pulse but as it was 5:01 pm they would have to wait until tomorrow. Upshot is they have raised a case and I will get a call next week. Motability have always been really good with me and I am hopeful of a good outcome. I will update in due course.
