Make a complaint to motability they’ll pay for your own choice of charge point.
I’ve had so many issues with BP they lied to motability saying they were installing in July when they hadn’t booked a date with me then gave me a date 2 weeks later.
I’ve been told yes, then no, then yes, then there’s a problem, then it’s all OK here’s a date, then no there’s a DNO issue (there wasn’t).
Look at it this way if they’re this bad now what happens if you need warranty support?
I’m booking a Hypervolt charger soon.
