Frozen account

My husband has had his account frozen by Capitec. When he asked about it they have told him that the account was frozen as a tip off for *****. Now i can understand if they feel it necessary for an investigation however he has provided what he was asked for. It is 5 days later and nothing has been done and we cannot use the money that we need to survive. They are very quick to freeze an account but cant be bothered to unfreeze it. There is another person who also needs to be paid from this and he cannot be paid as the account is still frozen.
