Poor Servive Delivery on NeoBroadband Fibre

So this is probably a rant, I currently have Neotel 10Mb/s fibre connection, the connection is provided over MW. <br> So I understand that my connection is a contended service, so I understand that I can not expect 100% of my 10Mb/s every second of every day, but over the last 3 months my connection has not been able to pass 6Mb/s since the start of may, I have been lucky once to get slightly higher than 5Mb/s.<br> This is what the connection is like. 24hrs a day.<br> <br> Neotel is a *******, all their service desk says is that it 5Mb is within normal levels.
