Hi, I joined at the weekend and offered a £50 discount on first month and was told to phone back today to claim it. So far two calls have said nothing on my notes about it. So I want to cancel the contract out of principle. So far I've been asked to speak to the Pre-Install Team to cancel and I tried earlier but gave up after 20 minutes. I'm now back holding on for 23 minutes and not confident about getting through to someone. I heard the customer service was poor. Any ideas on how I can get everything cancelled easily? Many thanks.
