"hi jason, iam with supanet and they want £50 to give me a mac code they say someone else deals with this what can i do regards john."
Charging to issue a MAC code is unusual, unfortunately since Supanet is not part of the MAC code of conduct this means that they are under no obligation to issue you with a MAC code either.
The charge you're talking about might be a cancellation fee since ISP's usually charge between £50-70 if you try to leave inside the initial contract period.
If you're outside of the initial 12 month contract period then you're being charged unncessarily for a MAC code. Orange is also considering a similar charge.
So what can you do? Well there are three choices:
i) Pay the £50 fee and switch to a more competitive provider
ii) Don't pay the £50 fee and instruct BT to switch off your broadband connection and then 2-3 weeks later your new ISP should be able to get it connected again, (this means a loss of service for a few weeks)
iii) Refuse to pay the £50 fee and fight Supanet to issue you your MAC code for free, (could take ages and cost money and more importantly they don't need to issue you with a MAC code as they did not sign up to the scheme.
Let me know how you get on?
.......having looked at that, it doesn't look like I have much of a leg to stand on :-(
bye bye broadband for a month or two :-(
