Money not given back

Having worked for Virgin Active health Club before we usually sign pension fund forms to tell us how much we will be contributing to the 10x investment company so that when we leave the company we then collect our investment from 10x, my contribution was 6.5% monthly which I signed and was filled. I exited the company in February and forms were handed in for my claim in March, a lady by the name of Tania Burt is the one processing everything as HR she 1st asked for my divorce decree which I explained to them I should have ticked the box Single then I got a mail saying my last contribution with 10x investments will be in March which every month from the month of October last year my money has been deducted monthly. I send emails and I am not being told what is happening and now all of a sudden 10x says they don't see any funds for me. All I want to know is where did my money go to where in fact is all the money that has been deducted every month without fail I have payslips as proof and bank statements as proof nobody is getting back to me about it because I was supposed to receive it by 20th April 2021 Virgin Active is not getting back to me as 10x already got back to me all I want to know is where did Virgin Active lose my money because everyone is quiet now. Where is my money? Virgin Active is such a ******* I need my money
