FNB was unable to assist in retrieving funds from Oriel Water and Leak Detection

I had paid a plumber, Oriel Water and Leak Detection who banks with Fnb in October 2019 twice via EFt as I did not receive an sms confirmation for the first transaction. I went to the bank and they gave me a form and said that they may not guarantee the reversal of the second transaction. So the plumber did not pay back the money but said that he would complete the job. In January 2020, he demanded more money and did not come to complete the job. I went to the branch and they told me and where unhelpful. I went to the police station 6 times and got various responses but they were unhelpful so it was a waste of time. I was told to follow the legal process via small claims court even though I think it is theft or *****. A letter of demand was issued and I was told to go back a month later to issue a summon to court but lockdown started. Today, I saw a post of a lady who ordered pots and paid for it but it was not deleivered. Caapitec opened a case of ***** and blocked the account so the lady was forced to return the money. I was surprised to see that a few people rep**** to say that their bank assisted them in similar situations. Hence, I am raising this request.
