Started a new business recently and. although I've registered to the telephone sales preference it takes a few weeks to initiate. I'm totally sick of people ringing to get me to take up 'special offers for new businesses like yourselves'.
They get you in a corner, believing they really are from BT (until you discover that your bills will now be coming from TML, your approved local BT wholesale provider)or that you 'agreed' to place an ad in a local Crime Prevention booklet (particularly odious lot, those ones). It's got to the point where I don't want to answer the office phone any more.
They are a shower of bastards.
