I see. So a case of wait it out then? Surely they can't charge for this level of service?
For comparison and to show my equipment is working ok, here are similar tests from this morning:
I understand there is a legacy network which VM use for the 10mb service, which is often less congested. If I phoned up and asked to be "downgraded" onto 10mb for a while (until they fix the problem on the 50mb network), would this mean I would be using the legacy network and hence experience less congestion?
