Extremely poor service from SASFIN BANK LIMITED

we have one employee who banks with Sasfin bank, on the 1 November 2024, we paid our employee who bank with sasfin 110 000 instead of 11k, we immediately reported with the bank and we requested that they return the money, they requested to talk to their client who is our employee, he confirmed that and they requested that we send the documents, we send all those documents they requested, thier client( our employee) even went to the bank to confirm that what we reported is the truth, we have called them several times , all we want is that they transdfer back the moneyh as we want to use it for important things. they cant keep the money when they have verified everything and find everything to be true, we sent various email to the following emails ***; ***; ***. out of desperation and yet we haven't been assisted. we have more than 6 employees that banks with them and if this is not resolved, we will have no choice but to ask their clients to change banks that we can pay their salaries to as dealiong with sasfin is a head ache.
