Will not stop spamming me

After losing 100s of thousands with old mutual and eventually being penalized for moving my business elsewhere they are now harrasing me with their spam. Today their in house finalcial advisor called me 5 times, after I have told them several times not to contact me. When I asked him to log a complaint because of this behavoir he said the best he could do is transfer me and waste more of my time. As an oganization I have no interrest in doing any business with Old Mutual again, in the more than a decade I was a customer you lost me money while making sure to collect all your fees, overdeclared profit which increased my tax liability and are now ingoring the law because you feel your marketing is more important.
