I'm not the most organised person firstly - we moved into this flat 5 years ago and I just went with the first broadband company that called me and offered broadband. It has been on constant renewal ever since. No letters through the post or anything, just constantly renewed automatically. As I say I have no letters indicating who my broadband company is even. I have noticed the package has ballooned to 28 pcm for a basic package. I've seen a cheaper deal for 18 pcm. I tracked the company who takes direct debit out of my account. Their website says they only supply commercial premises, which is strange as our house is very much a residential premises when I last checked...anyway I emailed then a week ago. No acknowledgement or response from them since. Now, can I just go ahead and switch to a new supplier without informing the current provider? Oh, and I need the telephone number for our connection (which I don't have a clue what that is as I only use my mobile - don't even have a landline phone). How can I track my phone number?
