What length of cable do you require?
I think VM can send out pre-made leads up to 3m (based on past topics on here).
If you need a longer lead you would need a non-fault tech visit for £25 where the tech would custom make a lead for you and check signal levels are OK via the new cable.
The primary place to report faults or for service requests is Customer Services on 0345 454 1111/150 if you have a VM landline or wait two or three days for a VM staff member to get to your post.
Thank you for your post. I'm sorry for any issue you've had with getting the coax cable.
I can certainly look to help with this.
I will private message you now to confirm your details.
Thank you for joining me in a private chat, as discussed I have now arranged a technician to add a slightly longer cable and also arranged a 3rd pod, as discussed please try a pin reset, push a pin/ paper clip in the reset hole at the back of the Router and hold in for a timed 1 minute, once done allow 15 minutes to settle.
