FNB Can't assist with blocking **** debit order due to covid restrictions

Good day.. Im Nonhlanhla On the 15th july an amount of R109 was deducted with a minus - R9 as I only had R100 in my account.. I also saw another R110 which I thought would be charged for the having is sufficient funds. On frid 17th I tried to call the call centre I never really got the help I wasted an hour and thirty minutes they kept on transferring me from one agent to another or that automated voice thing.. The money was reversed back to my account.. But I need to block this **** debit order... 0n the 20th I even went to a branch stood there for hours I was assisted with calling the helpline again and I was told to connect the company that debited from my account.. I feel that's not fair.. I need to call *****s and ask them not to take money from my account as the bank can't assist due to covid changes.. We save money in the bank as we feel it's safer than putting in under our beds.. *****s are taking our last cent and the bank can't assist.. Please do something about it.. I need to permanently block this debit order from taking my money and report them for *****.. Sent the same message to FNB as a complain no one got back to me..
