Unhappy with Unlimited access to my account before I approved their policy

I was approached by the guy called Lucky who sold me a clear pitch but said the Unlimited people will call me to activate my policy, that is not the case, there is a debit order already approved in my bank account. I haven't even spoken to the company for the them to even debit. That sucks as they only crave to check my details if they are correct and not bother with following up with the agent promised will happen. Can the Unlimited company remove their tracking on my account as I haven't spoken to the people who will call me to confirm if I want the policy or not
