Disgusted with Standard bank customer service

I am disgusted by Standard banks service 3 weeks ago I change my number and email at the bank I've been in 4 times inside the bank and phoned standard bank numerous times to activate cellphone banking and internet banking nobody helps me and then today I went into the bank again and finally someone was able to help me but I had to get back to work so the lady said the bank closing at 3:30 but she will let me in just before 4 to help me she will arrange with manager When I got their at 3:45 Northmead square Standard Bank Benoni, they said theres no appointment I am so disappointed and disgusted with this service and they definitely will loose me as a customer
