Poor customer service

Nedbank Eyethu mall in orange farm they always short staff..... When u there for the service they not digital enough u have to wait 3 to 4 hours... Not that there are a lot of people just bcz they have 4 people the whole branch to service customers...... Can the management review if this nedbank is living up to the nedbank standard and are they assisting people accordingly and are they short on staff or just a favor where a manager allows ppl to take leave without stratergising on how the customer will be service. One lady at sales and advise and she had one person for the whole hour. Please check this bank for us its not the 1st time I experience this.
