No help from Capitec!

My boyfriend and I both work for an online teaching company who pays our salaries into an app that transfers the money into our account. FNB thereafter contacts Capitec advising that the cashier who transferred the money into our accounts is being reviewed for *****ulent activities. Capitec puts our salaries on hold due to this and we have no money to pay our accounts and see to our expenses (This was done without any contact from Capitec querying with us as to what is going on). Capitec has not been helpful considering that we have provided proof that this is our salaries and we have been following up and no help has been provided. I have also requested a repudiation letter in order to get further assistance from the app that transfers the money into our accounts and we have not yet received it. I have spoken to 2 different team leaders who are refusing to take our calls nor give us the feedback we require. With regards to our "investigation" .. we have only received an email advising us on the things we already are aware of. I am utterly disappointed in the service from Capitec!
