Disgustingly bad customer service by Liberty

Massively frustrated and disappointed by the service of Liberty. I actioned a transfer from a company pension fund administered by Liberty by the way, to another product, again by Liberty, in October 2025. They claim they processed and paid the claim over to the new product in March 2026 but all my benefit statements and financial history show no such payment. The payment confirmation, tax directive etc have been requested multiple times and I’ve just been ghosted. The one they did send, was password protected with my ID number, but surprise, my ID number isn’t opening the document, again, when the document has been requested, there’s been no response. How much longer must I send emails and get no response other than the automated message. I’m at my wits end.
