Worst Service Ever

Yesterday went into the Mossel Bay Heiderand Branch to activate my APP and update my cellphone number. The lady that assisted seemed to be not in the moody updated my number and said that I'd receive a link to activate the remote banking. She left her desk and I was seated for 10min extra and by this the APP was still not working. I stood up went to her and told her its not working without even looking at my phone she said I should try at home. The most disturbing and disgusting service ever received from one of your branches. App still not working.
