Lack of service as a reminder to why my policy isn't with OM anymore

So on the 1st of September I wrote a email about changing my personal details as well as a small amount of money that was still to be paid out to me for a previous and now closed off policy. Countless up and down emails from a Zoe Mitchell who then escalated it (not sure why) to a Chantal Monnery who had every excuse in the book to not deal with my query. Kept saying she will find out or get back to me yet I am the one sending emails to follow up. Fast forward to the 29th of September, I asked her for her head of department as she was nowhere close to even helping me with my query, she just simply stopped replying. My policy number is ***7 and all I wanted to ask is that Old mutual pay out whatever money is due and the process thereof.
