Poor Service 2 times

Today I went to Nedbank Hout bay Branch for a card replacement and cell phone banking app activation . I waited for 34 min before I could be served . Took him about 15 min to process my card application , but he failed to activate my app telling me that maybe my phone is not compatible ( which is nonsense as I have been using the app on the same phone since last year . I request a help from another worker at front desk who also was useless .I left the bank frustrated and unhappy . Am reporting this poor service and incompetency of the stuff of this branch as its not the first time I leave the branch without good service . They don't derseve no star
