Account suspended for no reason

Your customer service is appalling. My banking app AND bank account have been suspended and no one from your branch consultants to your customer services can tell me why!!!!! When I went to the Mall of Africa branch to enquire why my access has been blocked, they could not assist me, all they told me is that they have to send an email to some department that flagged my account to be suspended for permission to unblock it, they can't give me a telephone number I can call and cannot give me a turn-around time for when this will be resolved. I then called your customer care line myself and was transferred to the ***** department where I was on hold for 30 minutes without actually speaking to a consultant. What exactly do you expect your clients to do in a situation like this during month end when bills are due??????? Your staff is extremely ***********; their level of service is appalling and their lethargy in resolving your clients' issues clearly indicates that you don't know the first thing about customer service. I will be closing my account, you are a sorry excuse for a bank!!
