Old mutual harassment

I frequently get calls from Old mutual insurance and no matter how many times i say im not interested i still get calls. The last call a few day ago i told the consultant i refuse to take out insurance with old mutual. As much as old mutual won't grant me credit to toy credit record, i also refuse to trust them based on reviews. My credit record is bad and old mutuals reviews are bad, so no i will not take any insurance policies with them and allow them access to my bank account especially with the reviews of people being debited on a cancelled policy. Stop calling me!!!!!!
