Despicable service from old mutual- Still waiting for a solution over two months later

I've had an awful experience with various consultants.

1. I have been attempting to transfer my pension funds for over two months. Every consultant gives me different information from the previous, I was requested to send an email with my new pension details, however, I was trolled and every person that responsed to the email had no idea what was going on. I have sent in emails which are going unanswered. Everyone keeps referring me to the claim portal, however, my pension fund is not listed therein. I have been sent from pillar to post with resolving this.

2. I went into a branch to change my banking details for my child's products, i was informed that they needed to send the forms to HQ and this would be sorted within 3 days, however, the debit orders still came off my old account which I dont use anymore. This has been a huge inconvenience.

I am now despondent and not sure how to get my funds transferred or update my banking details for my other products. Overall poor customer service
