Very poor and disrespectful service

Afternoon, so I have been trying to claim my provident fund since from April, they keep on requesting me to send the very same documents over and over again and there is no communication at all , so far i have sent those documents four times and nothing has happend till today so today I spoked to Salteb employees benefits, whom are the ones who make the payments they said they did receive any document of mine from Transport Sector Retirement Fund and they 'salteb' can not assist me until they receive those documents from TSRF since they are the ones who have been collecting my money.

What must I do now to get my Money after I have sent what they have requested four times already. I just want my money i'm not asking a loan from them
