Old Mutual quick to sell policies and deduct monthly debit orders but ignore their clients thereafter

I took out a retirement annuity and income/disability cover with Old Mutual. My OM advisor sent me my policy 5 December 2018. I immediately noticed inaccuracies in the underwriting. I notified OM in writing within one hour of receiving the policy. OM wrote incorrect information in the policy not me. I asked OM to rectify their mistake with immediate effect. I did not want OM to accuse me of providing incorrect/false information and refuse payment at a later stage due to incorrect information on the policy. To date OM has not made the relevant changes. I have sent three follow up emails and phoned OM directly. OM did not hesitate in deducting their monthly debit order from my account but it has been two months and they have still not corrected mistakes that they (not me) made to my policy. I am terminating my policy with OM and moving to PPS. I will not recommend OM to anyone. My experience is that they are quick to sell and deduct money but have no interest in responding to their clients once they have your money.
