bad service

I was employed by new national assurance company and after resignation they had to submit my pension forms to old mutual as correct and accurate for my pay out and claim process to run smooth and I resigned on the 12 of February and on the 24 of march when I do I follow up with old mutual I was told new national ticked that I have prior claims ,which might be because I owe the company some money or something, <br> the issue here is old mutual has not got back to me and tell me the delay and since they claim they sent the email to the company on the 12 march 2016 for more details on what is causing the delay they have never followed up with the company so that they get accurate information to pay may claim from 7 march to 12 march and today being 24 march they are folding their hands waiting for a the company to take as much time as possible to rectify the claim the submitted to them and again I feel it sabotage from new national and old mutual is just relaxed because the also don't want to pay my claim.. <br> <br> old mutual and new national must sort out their issues immediately because I want my money and they better rectify the bogus information on my claim form because I don't owe .
