Funds at Work Momentum- no communication and no payout

Been trying to claim my Funds at Work money from Momentum since the end of March. When I hadn't heard anything I sent an email and was told they hadn't received my withdrawal forms. I had the email from my previous employer and they had sent it but we resent the forms on the 13th of May they then said it was being processed and it will take 26 working days. It is now 28 working days and I have had no communication with them besides me sending a follow up. After 9 emails sent and all I get is a cc passing me onto someone else who never gets back to me. All other colleagues who have claimed have got their money in the allotted time with lots of communication. I expected better service from such an organisation. So disappointed.
