Hey there, @KG11. More than happy to look into your complaint myself although I've just responded to the thread you created earlier and I've offered assistance via PM. For consistency it's best to keep our conversation to one thread so please PM us with your details so that we can help you out.
Heya, I've replied to your PM - we'll chat with you there.
Sorry we didn't get to this earlier @Knotlaboy. How's everything going since your post? Have you been provided with a fault reference number so I can check into your problem's status? Alternatively you can send me a PM with your full name, DOB and account number so I can check your account notes.
The experience you've mentioned seems really frustrating, we're here to help though
