A reminder to everyone: Under OFCOM rules an ISP cannot withhold issuing a MAC because of a dispute over outstanding fees - they must issue the MAC within 5 working days of a request.
See
http://www.ofcom.org.uk/telecoms/ioi...vogc150807.pdf
See Annex 1 starting on page 73.
Para A1.5 specifies the 5 days
Para A1.11 gives reasons why they may refuse to provide a MAC - refusal to pay a termination fee is NOT a valid reason.
