Nedbank and Old Mutual not honouring scheduled payments

Nedbank Queenstown branch We made our investment with Nedbank and the financial advisor allocated to us apparently also works with Old Mutual. We invested a n invested for a long period and also one with monthly allowances. We have been experiencing problems as a result we did not get the scheduled payments for 2 months now. We are students and depend entirely on this money. We have been unable to even buy food because of this inconvenience.
