Delay on payments

i recently left my old company who i had the pension fund with. 30 Nov was my last day. My documentation was sent through to A/ F & it would take +/- 10 working days for payment to be made. i received an sms to say the payment was rejected due to name validation issues. i then contacted A/F & they advised me that it was because my surnames didn't match, i recently got married so my surname did change. i sent all relevant documents through & was told it would take 3-5 working days to validate the info, after that my payment will be released. On day 5 i phoned to confirm that everything was still in order, i was advised to phone in the afternoon so that they could investigate. i phoned back at 1pm & was told that there was nothing they could do because the admin office left at 12. i have been phoning everyday since wanting feedback on my claim & all i keep getting is that the admin office is waiting for forms so that they can validate my claim. which was supposed to be done within the 3-5 day period they told me it would be done. i would really like this to be looked at & get some feedback asap!!!!
