Bad service

Good day, since last week (7 working days ) I tried to activate the FNB app on my new phone, up until today it's not active. One branch in Cape Town try to activate it, a "consultant" contact me and told me to not to try again within 48 hours, it didn't work, someone from the "technical team",contact me without any success, how can I trust them with my assets and money if they cant assist with this kind of service, I was one of those who said that Fnb atms all over available and convenient, I will never recommen First National bank, their service went down to non existent.
