Capitec has put a stop status on my savings account funds which were supposed to mature end of March 2019. Now I can't access my money which I desperately need!

I opened a tax free account which matured but I went to the bank to access the fund it had a stop status the consultant tried to contact the service recovery department but nothing happened and he logged a query I Waited for the call nothing happened I went to another branch the next day the lady said she ascaled the query I should receive a call but nothing.
