Policy renewal

The agent I spoke to was helpful and she did provide the information I needed. However, the renewal process was poor. I did advise an agent that I wanted to renew my policy. I was however told when they eventually came back to me that this is now treated as a new policy and I now have to wait 3 months should I need to claim. I have repeatedly asked for the manager to contact me to discuss this.and they have not done so. I am very dissatisfied with this as I have been an Msure customer for many years.
