Pension transfer assistance disappointing

Momentum agreed to assist me with my pension transfer from the UK. They apparently are registered with the HMRC to accept these transfers. I started with the process in July 2014, the forms provided by the UK were completed and forwarded to Momentum for their further completion. At the time I used a broker to assist me. The process were hold up every time due to them not providing the correct or incomplete information up to the stage where the UK requested for the whole process to be started all over again as the time lapsed was too much. The process was re-started in July 2015. This time I decided to deal with them directly and posted the completed forms personally to the UK. Everything went smoothly and the UK was about to transfer the pension fund when they could not find them on the registered list as per the Certificate they provided. Now everything is on hold again. Apparently Momentum in Klerksdorp has handed it over to their legal department (19October2015), I have had no feedback. How can they agree to assist if their registration is not in order? If it is, why don't they sort it out with the HMRC. After 16 months I am still waiting to get my pension transferred.
