Alexander Forbes not responding to claim

I was contacted for an unclaimed pension benefits from Alexander Forbes. I completed the forms and sent documents that was requested on the 22 January 2024. It has been a disaster to try get updates of what was going on. I was told claims processing and payout in 10-12 weeks. It is now 7 months and still nothing has been done. To get in touch with them takes so long as you have to use a call centre. You speak to a different person every time. They all say it's being processed. I have written numerous emails, even to the escalation email address. What a nightmare. I am so shocked by the no level of interest. No feedback and no one who can help me. I hope to never have to deal with them again.
