Unhappy and frustrated

First of all the service is extremely bad, you wait up to an hour to be assisted (FNB tsakane mall). Swiped my card today at Pep it declined then we swiped again only to find that it processed both purchases which to me is unsafe because I wouldn't have picked it up when I logged in on my App. Pep told me I have to go to fnb to get the transaction reversed & I'll get my money in 14 days. I'm seriously starting to regret changing banks to fnb
