Constant attempts to phone me

I asked for a quote from Outsurance in December. I told the call centre agent to email me the quotes and I will reply after I'm back from holiday. The next day was Christmas Eve. Then the constant calls started - I explained to the lady I was going on holiday and will look at the quotes when I'm back. It was like being stalked by someone with mental health issues. Harassment is a pretty low sales strategy. I rep**** to their email with the quote declining their offer and informed them my current insurer is cheaper anyway and to please stop calling me. I still see they are attempting to contact me despite sending them an email declining their quote. Please stop calling me Outsurance. In the future if my current insurer is more expensive I will consider outsurance but calling me constantly will not change my mind. I don't answer these calls and I resent the intrusion.
