Provident fund **** from Momentum

I changed jobs at the beginning of September and I have been trying to contact Momentum since then in order to access the money in my provident fund. I have sent e-mails to a certain Adelle Landsman (Administration Manager), but the only response I have had is an automated reply every time which states that all client queries will be responded to in 48 hours - completely untrue. At this stage, it feels as though I have been ****med out of all the money that I have been "saving" towards my retirement.
