Worst service from Capitec Bank

I’ve been using Capitec bank for more than 10 years,my account with them is frozen at this stage because of 1 customer that **** and did a ***** report for 3000,they didn’t even conduct an investigation on this,in so many years they never had a report of this nature but with one false incident my account got frozen without an investigation,am so sad and upset at the same time and I feel this is so unfair.
