@Ropata is this sorted now?

Yes. I rang again at midday and instead of going through the menu to technical support, I went to new customers and whadya know, it didn't even have a chance to ring before someone picked up. They put me through to someone who logged the fault and had a tech round within 2 hours. I had damaged one of the pairs as I thought I would re-do the cable management while it was broken but it's all fixed. Plus it's now virtually invisible since I tucked it under the new cladding.
