Homeless cause of fnb

Dissapointed with fnb yet again, i was left stranded this weekend with no food no shelter in a town i knew nobody because a client of mine was unable to get ahold of me and he lodged a complaint with he's bank that i may have ****** an amount from him with instructions from standard bank fnb placed a hold in my account, upon calling them i was made aware of the complaint i was able to make contact with the client immediately and the client and i had come to a resolution, fnb advised that both the client and my self need to provide affidavits to have the hold removed however fnb could not provide me an email Adress to send through the docs because they claim the case was not assigned to an investigator.. So they blocked my account with the instruction of a client but refused to unblock it yet the client dispute has been resolved please help
