Bad service from Liberty with **** escalation channels

It looks like Liberty still hasn't catered for the two pot system. It takes them weeks and multiple follow up requests to send through a POP for a S.14 transfer, but in the incorrect format that doesn't show the different components of the funds. Now with more then 5 follow up calls and emails we can't get the amended Proof of payment from them. They keep "escalating" and breaking their SLA's, and then we have to follow up from our side for feedback.
