what a nightmare

Oh my word this company is a nightmare. They call we to take a new policy which I say I don't want, they continue to hound me to take the next policy which I again say I don't want. Then a supervisor calls to find out what else they can do to get me to take this car insurance and they offer me a lesser excess than my current one. So they send me the quote and insist I give them a debit order date while I review. Now I've reviewed and I now want to please cancel my policy, I tried to call, i was left holding for 5 minutes and then got through to someone who demanded an explanation as to why I want to cancel, I said I'm happy with my current provider and they want further explanation. I asked to please stop asking questions and just cancel, then they want to first get an explanation about why I'm upset. I tell them I'm upset because I want to cancel without a million questions. They want further explanation so I hung up. They call back and again they want explanations and chances to offer better so i insisted they stop asking questions and just cancel and again he just ranted on and on pm g hung up. What an absolute nightmare
