Hi,
This is my first post, and it isn't related to banks, so if this is too off-topic, please feel free to remove it.
My ISP, V21 has had it's phone line services withdrawn by it's own telephone line provider. When trying to access the internet last night, I was directed to a 'walled-garden' site of another ISP, who was very kindly offering to 'rescue' me - for twice the price of my current provider with a minimum 12 month contract. I am unable to go to any other websites.
If I choose not to take this service, BT will be informed on 24th November to cease my broadband service. This will take approximately 10 days.
To me, this seems a very agressive approach. I can't change my account before BT have carried out the cancellation (around 11th December) as I need something called a Movement Authorisation code (MAC). The telephone line provider has these codes, but will not issue them to anyone as they say it's in breach of their (temporarily withdrawn) contract with my service provider. Nor will they issue them to my current provider.
I'll get there eventually

My question is, as this MAC key is specific to my telephone line and therefore is data that relates to me, is this a breach of the Data Protection Act?
I've phoned Ofcom and BT, but they were not able to offer any assistance.
Incidentally, my current ISP has issued a free dial up number, so I'm not completely abandoned
Any feedback will be much appreciated.
Thank you.
