Yes the phone lines need to be opened for such cases, the excuse of black friday is not really good enough now. This seems a new thing from OCUK, never not known them to resolve issues quickly and be easily contactable. Not good

.
Come on guys sort it now, this is an expensive purchase and should be dealt with accordingly.
@MrThompUK I did think you were jumping to conclusions when they didn't reply within 24 hours but I would have thought some resolution would have been done by now and at least to confirm to you they are working on it and trying to resolve the issue with your new pc.
Also I did ask you if you are using your own monitor and cables or was it part of the pc package you purchased as you didn't reply to that as the issue may still be the monitor or cables used.
