Everytime in two to three months this useless bank freeze my account without notifying me mxm

Poor service Ive been with other banks eg standard bank, fnb but ive never received such a poor service like this. Nedbank doesn't care about us it just running a business. They froze my account because of fica verification which i understood but now every 2 months they just freez it without notifying me, when i go to the branch they cant help me they say their network is down like seriously guys we have to use our airtime to call your call center for you to do your jobs. Im now stuck i have to borrow money because of your poor service. I wish i never joined this useless bank mxm.
